sentimental analysis

admin — Thu, 11 Sep 2008 15:18:19 +0000

An important part of our information-gathering behavior has always been to find out what other people think. With the growing availability and popularity of opinion-rich resources such as online review sites and personal blogs, new opportunities and challenges arise as people can, and do, actively use information technologies to seek out and understand the opinions of others. The sudden eruption of activity in the area of opinion mining and sentiment analysis, which deals with the computational treatment of opinion, sentiment, and subjectivity in text, has thus occurred at least in part as a direct response to the surge of interest in new systems that deal directly with opinions as a first-class object.

Basic HTML Tags

admin — Sun, 10 Aug 2008 19:38:15 +0000

Basic HTML Tags
Most HTML tags come in pairs, an opening and closing set. The text to be formatted by the tags is written between the pair. It is essential for both tags to be present for the document to work correctly. All tags are enclosed in left and right angle brackets (<) and (>). Closing tags are preceded by a backslash (/). The tags are not case sensitive though you may wish to keep paragraph related tags in uppercase and phrase/word related tags in lower case inorder to distinguish them more easily when scanning your file.

Tags to open and close an HTML document
All HTML documents should begin with the following set of tags:

<br /> Write your title here.<br />

Begin your main body of text here.
All HTML documents should end with the following set of tags:

Headings
Headings come in a number of levels or “sizes.” The major title of an HTML document is usually the largest,

. Heading tags are used in pairs, with the actual text of the heading between the two tags.

Heading Three
Lists
Use these tags to create ordered (numbered) and unordered (bulleted) lists. List tags include pairs to designate the entire list and individual tags to mark each item within the list.

Links
Hypertext links allow you to jump to other HTML files you’ve created and to sites around the Internet. It is necessary to know the URL for the site you wish to link to. The tags for a link include the URL (which is enclosed in quotation marks) and the anchor text (the text that you click to jump to the link).

anchor text

http://www.lgoogle.com/“>
UW Libraries Home Page

UW Libraries Home Page
Inline Images
Images can be a bit tricky because of the variety of image types. The easiest to work with are .gif and jpg images. You can scan in your own images using the scanners in Suzzallo Library or you can download an image from another Internet site (be aware of copyright restrictions). You should also add an additional message for non-graphical web browsers such as lynx which will describe the image.
SRC=”test.gif”>

Other Useful HTML Tags

Use to create paragraphs. You must use this between each paragraph or else all of them will run together.

Use to make a line break.

Use to make a line across the page.

SEO Tips for Small Business Websites

SEO Tips for Small Business Websites
Simple techniques that will put you ahead of the competition.

Every day I help dozens of small businesses optimize their websites to improve their visibility and rankings on search engines, and every day, I ask one client to make many of the same changes as the last.

Small business websites generally face some major obstacles to ranking well on Google, and competition is rarely one of those obstacles - at least not in this stage in the game as most small business owners still seem oblivious to the potential in being ranked first in search engine rankings - of course, competition varies within industries (apologies to all the real estate agents that are reading this). In my experience, once these obstacles are out of the way, small business websites (for auto repair shops, day spas, shooting ranges, etc.) climb very quickly to the top spots on search engines.

So what does it take to step ahead of the competition?

1. Design it right - the first time
Small business websites have two inherent enemies: the owner, and his/her budget. I wish I had recorded (because I promise you’d be surprised) all the times I’ve heard:

I made this site myself with Dreamweaver/SiteBuilder/[an online tool] but it doesn’t seem to be appear in search engines

I can’t make the changes you asked for because the tool I built my website with doesn’t give me access to the HTML/my web designer says that those changes are just too hard (web designer is inadequate)

The best advice I can give (and as a web designer you’ll hear this from me again and again) is to find a professional web designer. Small business owners often either look for the cheapest, most affordable solution and sacrifice quality and the ability to test and improve their website, or they try to do it themselves, thinking that the FrontPage 2000 class they took in High School qualifies them to make the company website - besides, it saves money, right?

There are plenty of affordable web designers (no I’m not talking about the friend of your nephew’s girlfriend) that will work with you to make a website that reflects your brand, product, and customer base.

Don’t forget - websites are promotional. You wouldn’t pay for a cookie-cutter mailer or pay for billboards on roads with no traffic (see where I’m going with this?) - so don’t expect that using the cheapest/simplest web builder or template is going to be a smart investment.
When it comes to building a website, think in the long-run. A website that can’t be found is a waste of money; same with a website that doesn’t sell effectively. You shouldn’t have to pay a lot for a well-built website, but you’ll be paying more if it is built in a non search-engine-friendly way or in a way that doesn’t allow you or your designer to make changes to the HTML code on your site.

2. Use keywords
Please - include keywords on your site. The copy (text not contained in images) on your site is the only indicator that search engines have in determining what your site is about and what keywords it should rank for.

If your site doesn’t say “Plumber in Reno, NV” anywhere on your site, then it will never rank for that keyword.

When determining keywords to target, think of what you would type to find a similar service/company/product in your area. When you are searching for Pizza in Athens, GA, you will probably type something along the lines of “Pizza Athens GA” - this works with nearly every industry. The “[industry/category/product] [area]” keyword model is a good example to follow.

Where to place keywords: Once you have chosen a few keywords to target, use them in an intuitive, relevant way in your body copy. It shouldn’t be hard to include them if you talk about your area and industry right on your home page (which is the page you should focus on the most - none of those “Enter Here” pages that waste users’ time and tell search engines that your site is about “Enter Here”).

3. Avoid using Flash
As a designer, this has always been a difficult recommendation to make. I love Flash - I think it’s pretty, and it is also (especially the latest version) versatile, interactive, and makes for some great applications (see jooce.com). But until July 1, 2008 it has not been search-engine-friendly. Google just began indexing Flash, but its SEO value has yet to be tested and determined so my advice is still to only use Flash for logos, banners, and other small graphical calls to action that don’t need a lot of text.

4. Take advantage of title tags
You don’t have to be familiar with HTML to master this one (very) helpful technique: using title tags correctly. Title tags are found towards the beginning of your HTML and all you have to worry about is the text between the opening <title> tag and the closing tag.

Too many websites don’t take advantage of the SEO value that Title tags have to offer; they use titles like “Home,” their domain name, or their business name. I recently read a very good article that discusses using your business name in title tags - it is certainly worth re-thinking.

Research has shown - and the experts agree - that title tags are one of the most important factors that search engines take into account when they index your website.

How to use Title Tags correctly:

Do:

Make the title tag on each page of your website unique
Try to keep it under 65 characters (that is all that is visible on search engine results pages)
Include keywords that are specific to the respective page, and describe the theme of the content on that page
Don’t:

repeat keywords
repeat the name of the page (instead of “About Us,” write “About [Company Name] - San Diego Dentist”)
worry about fitting in every keyword you want to rank for - just add the most important one, or - if there is plenty of room and it makes sense - two
forget that this is what users see in search engine results - so make it relevant for users (not just for search engines)
5. Promote your site
I am always surprised that my clients want to be found on Google, Yahoo!, and MSN, they are willing to pay me for it, but they haven’t spent the time to add their business profile on Google Local, Yahoo! Local, or MSN Local. Here are the links to these business profiles (this gets you on Maps and business directories for all three search engines:)

Google Local - Gets you in local listings and Google Maps

Yahoo! Local - Gets you in the Yahoo! business directory and maps
Live Search (MSN) Local Listing Center - Adds your business to MSN Live maps
It is also helpful to add your business to these directories:

Dmoz Open Directory Project - adds your site to hundreds of online directories.
InLocal.com Local Business Directory - there is a free version, and the paid version gets you into over 70 directories.
YellowPages.com
SuperPages.com

Top Ten Ways To Improve Your site rank

admin — Sun, 10 Aug 2008 19:31:35 +0000

The practice of search engine optimization (SEO) is part science and part black art. Keeping up with what search engine algorithms deem most worthy for high page rank is ever changing and highly secretive. Aggressive SEO hacks who try to “cheat the system” may earn a web site a high rank one day, but possible banishment the next. Beware of optimizers who promise you #1 rankings; they may do more harm than good.

It’s no secret that search engines (such as Google and others) like content — lots of it, fresh and steamy. The more pages you publish in your area of expertise, the more exposure you will have to the search engines (they love archived material too). And the more strategically you headline, title, metatag and link those pages, the higher they rise in rank.

While all search engines work a little differently, they all attempt to provide the best, most relevant information based on search queries. So, I guess what I’m trying to say is: Publish. And be relevant. I’ve had great success (see Google Successes) with client web sites scoring well on search engines by publishing pages that avoid schemes to “trick” search engines and implement the following tried-and-true tips for search engine success.

1. Use keyword-savvy “page titles,” and strategic and proper metatagging on all pages.

2. Allow search-engine robots easy access throughout your site via text links, alt-tagged navigation icons, or a site map.

3. Register your URL with major search engines, directories and specialty sites, as well as select paid directories (such as Yahoo!).

4. Use strategic home page content (keywords in context in HTML text).

5. Use hyperlinks to further weight in-text keywords.

6. Encourage in-bound links from other relevant sites to your pages.

7. Add an integrated web log to your web site.

8. Add/update content frequently. (Write dammit!)

9. Avoid Flash-based opening home-page screens, improper metatag code, as well as any schemes meant to “trick” search engines.

10. Get a search-engine optimization audit for your web site.

top mistakes that a seo can make

admin — Sun, 10 Aug 2008 19:29:37 +0000

If you’ve tried your hand at building an Internet-based business but haven’t yet reached the success you want, find out about these eleven deadly mistakes and how to avoid them.

Mistake 1 - Not Treating What You Do as a Business.
The difference between a hobby and a business is that a hobby doesn’t make you money - it costs you money.

If you’re earnest about starting a profitable online business, approach seriously and focus on generating revenue. Treat your online business as you would any regular business.

Mistake 2 - Being Distracted by Too Many Good Ideas.
You can light up a room with a light bulb, but you can cut through steel with a laser beam. The same is true with your effort and ideas.

Too many Internet-Entrepreneur-Wanna-Be’s lack the will power to stay focused. Chasing too many ideas at the same time often leaves them exhausted, frustrated, and with little result to show for their hard work.

The key to success is to select one business idea and to develop it completely before moving on to another project.

Mistake 3 - Not Selecting a Specific Niche.
Perhaps the biggest mistake of all is trying to be everything to everyone. You can’t - so stop!

It’s very counter-intuitive to focus on a smaller slice of the market and most people are afraid to do it. But when you do, your business will grow faster, and you’ll be more financially successful in less time.

Mistake 4 - Falling in Love With the Wrong Product Idea.
Even the most experienced entrepreneurs fall into this trap from time-to-time and develop products without doing any research. Before you devote any serious amount of time and effort to developing your new ideas make sure there is a demand for the type of product, information, or service you want to launch.

If you need help with selecting an ideal niche market for your business and finding out which products you should develop first, take a look at this fast track training program (http://www.infoprofitfasttrack.com/vipinvitation.html).

Mistake 5 - Falling for the “Get Rich Quick” Scheme!
Remember the old adage “if something is too good to be true…”? It’s alive and well on the Internet.

Countless people buy into the idea of making millions online overnight. Sadly, they buy into programs hyped up with empty promises only to find themselves “out of cash and out of luck” a short while later.

Be aware of spammers, illegal money-winning scams, and buying “ready to go businesses” that are “hot but will sell for cheap”! Before you fork over your money investigate if those hot businesses have ever made a dime for their current owner.

Doing your homework will save you valuable time, money and many sleepless nights!

Mistake 6 - Going Into It, Instead of Growing Into It.
While the Internet makes it easier to reach your potential clients, you’re still building a business - and that takes time. Don’t tell your boss you’re quitting today because you started this hot new online business last night and you’ll be “rolling in dough in no time flat!”

First make sure your business idea works and is profitable.

That’s one of the advantages of Internet Business - you can start small and step-it-up as your business starts getting sales and generating profits.

Just be sure you can consistently replace your current income before jumping ship and telling your boss to “beat it”!

Mistake 7 - Being a Copy-Cat!
Quickly - what is the most popular business on the Internet? You guessed it - it’s how to make money on the online!

It seems that everyone who has bought a course on making money online is credible enough to teach this subject a week or two later!

Don’t fall for the allure of easy money - because it’s only a perception. In reality your chances of having a successful online business are much greater when you are different from the pack.

Mistake 8 - Wasting Time and Money on Developing Pretty but Useless Websites.
A bad idea is a bad idea - no matter how pretty you dress it up. Many people waste precious startup dollars on expensive but needless graphic design work, pretty logos, and complex web design.

In reality, many businesses can be simple and inexpensive to get off the ground. In fact, a simple site with little or no graphics will often make more money than one with all the latest bells and whistles flashing all over the page.

Think - what is the core concept of your business. Outline it on a single sheet of paper, then implement it fast in it’s simplest form. You can always give it a makeover and make it prettier if it’s successful and profitable.

Mistake 9 - Not Building Relationship with Clients.
“Even though you don’t know me from Adam, I want you to take out your wallet and give me $20 - in exchange I’ll make you the King of the Universe!” What!? You don’t want to give me your $20? What
a surprise!

Most people think about starting a business online in terms of getting a quick sale - with no prior relationship with their potential clients at all.

In reality, you’ll be more successful when you make your first goal to collect contact information from potential clients and follow up with them on regular basis.

It’s much easier to “sell something for FREE” than trying to convince people to give you money at first.

Make it your goal to prove your credibility online and make your business all about relationships with prospects and clients, and you’ll build a thriving online empire.

Mistake 10 - Calling It “QUITS” Too Soon!
If your new online venture isn’t making money at first, don’t walk away from it too soon. Many entrepreneurs have multiple “failures” in their background - which in reality are lessons in what didn’t work.

Evaluate your ideas and get help with gaining a new perspective on what you’re doing. With some new ideas you might find a new way to position your business differently and make it profitable.

Or maybe you simply need to give it more time to gain the traction and momentum you want.

Mistake 11 - Being too cheap!
While it’s a good habit to be thrifty with your dollars, don’t confuse saving money with being cheap. Remember the price you’re paying for things isn’t always expressed in money. It’s also the time, effort, and lost opportunities you can’t take advantage of because you lack the know-how or are busy doing low-level tasks.

Smart online entrepreneurs continually invest in their Education. They buy marketing training programs, time-saving software tools, and systems that allow them to grow businesses faster with less
effort.

The best news is that getting good basic training in how to start your own information marketing business doesn’t have to be expensive.

How search engine works

admin — Sun, 10 Aug 2008 19:27:37 +0000

Spider:
A spider is a robotic program that downloads web pages and looks at the code of the page. The spider doesn’t have any visual components at all, if you right click on most web pages and go to view source that is what the spider can see.
Crawler:
While the spider is downloading pages, it is the crawler’s job to strip apart the page and look for links. It is the crawler’s job to look at the links and then decide where the spider should go next determined on the links or a pre-defined list of URL’s.
Indexer:
It is the indexers job to analyse different aspects of a web page. It looks at Entities such as, titles, headings, links, text, constructs, bold, italic, and other style portions of a page that are ripped apart and analysed.
Database:
The database is where all the results and pages are stored, considering that there are an estimated 10 billion web pages on the Internet this can take a huge amount of storage space, which will be increasing indefinitely.
Search Engine Results Page:
The results page is where the clever stuff takes place; this is where the engine decides which page matches the query that was entered in the search box of their home page.

seo tips, how to optimise your site

admin — Sun, 10 Aug 2008 19:24:28 +0000

Top 10 SEO Tips

The following tips are not necessarily in order of importance, but are in the order you should consider when building a new website from scratch. My top 10 tips ranked by order of importance for high rankings are displayed elsewhere.

Know your geographic market and ensure your domain has the correct TLD.
If your primary market is the UK it is important to use a .UK TLD and ideally have your domain hosted on UK based servers.
Include keyword in Domain name (using hyphens if necessary).
This doesn’t mean having a domain name like keyword-keyword-keyword-keyword.com try to stick to the one hyphen and not read as spammy. A good example is a site that sells wheelchair ramps with the URL of the site being www.wheelchair-ramps.co.uk
Create as much content about your products or subject as you can.
After doing this divide in to 4 or 5 sections (this will help later when creating your navigation structure)
AFTER you have your site content start keyword researching
There are tools you can use for keyword research; Wordtracker and The Google AdWords Keyword Tool to name but two. I personally use a combination of the Google Keyword Tool, Google LSI and T.J. Common Sense.
Decide on 4 or 5 primary keywords to use as main sub-sections
Ideally have an idea of 4 or 5 main keywords, call them your Primary Keywords and then try to position secondary keywords with the Primary Word most closely associated with it.
Sit down and sketch out your navigation system
Put a lot of time in to this and play around until it is right, use Primary Keyword as headers for 5 main Sub-sections and use secondary keywords as headers for content pages under each Primary Keyword
Re-write content using knowledge previously gained about keywords and phrases
This doesn’t mean totally re-writing and stuffing the page with keywords, it requires writing paragraphs ensuring the right phrases are in the right places but isn’t obvious that the phrases are written for the search engines. Do not write too much information on each page and do not stray of in to writing about something else.
Structure each individual page
With your content rich, keyword balanced page written, you now have to create the page structure. Each page should be seen as an individual website.
Starting from the top,Page title should reflect the content of the Page ensuring you use the primary keyword for that Page Meta keyword tags, (although not overly important), should list 4 or 5 individual keywords related to the Page you have created.
- Meta Description tags, this should be a short concise description describing what the Page is about. This is very important as a selling point as you can manipulate the search engines in to displaying this when the person searches for the keyword used in the description. A favourite of mine is “Provides information about the latest KEYWORD now in stock and available online” or words suitable for the product.
- Avoid bloated code by using external style sheets and minimum coding.
- Main page layout was previously discussed whilst sketching the navigation system, but it is important that all links are seen by the engines and are using the correct anchor text related to the pages they are pointing too. Avoid using javascipt for links and if you have to use images ensure you use the correct alt attributes. If the page has too many links on it and looks messy this can be overcome by using a combination of css and javascript to create drop down boxes, but should only be used if you know what you are doing. If you have the opposite problem, and want to include links on the page but not necessarily have search engines follow them, this can be achieved using drop down option boxes.
- With yout general layout and your linking structure sorted you should now sort out your headings. The main page heading of the page should use your Keywords and be in H1 Tags, this should be followed by your most important paragraph, ideally working down the page you should use secondary headers from h2 to h4 (always using the keywords if possible)
- If you have used images on your page ensure keywords in the Alt attributes, this doesn’t mean keyword stuff them but just describe the image using the keyword.
Proof read your completed page and get a 2nd opinion
With your page completed try and get someone to check it for you to see if it reads to spammy and to see if you have missed out any obvious key phrases that should be on the page.
Construct your site.
With the previous procedure completed for all pages it’s now time to put the site together. Simply use the previously devised linking structure, group similar pages together under appropriate sub headings and ensure all links are active and using correct anchor text.

What is the best programming language?

admin — Sat, 09 Aug 2008 22:47:44 +0000

I have experience of using perl, php, c#, visual basic, c/c++, java and also seen simple sample program of other languages. I think c++ is the best programming language. Pointer is oviously a problem for beginer but you can easily avoid them.

So why so many languages? Is there is technical reason, or is it just commercial war?

I love these features to be present in a modern language

c like syntax with { bracket
included assembly facility like D programming language. looking at D feature it seems it is superior than C# but digital marsh can only do so much competion with microsoft at this stage.
built in flex/yacc facility. like i can select syntax i want but program will be converted according to my choice of converter. For example i like ruby syntax then i write the code in ruby and compiler automaticaly convert them to a intermediate language. .NET is doing that but i am talking in programer level by simply using a config file. like compiler.exe program.cpp syntaxconfig.txt
built in parsing like embeded html and php code. in same program .
cross platform without recompilation

Do you like to add more criteria or have criticism?
