- Panei San added an answer:What tags are more suitable for main content extraction from HTML webpages?
I am interesting the Content Extraction from HTML web pages. Now I use the HTML tags for dividing the block of web page and use the tag-to-text ratio and anchor-text-to-text ratio and title density to extract main content. But all of HTML tags don't appropriate where content extraction. SO I want to know what tags are more accurate and more suitable for web page' cleaning? Thank You all...
Thank you all!
I really want to know that I consider the content extraction based on Line-block concept. The line-block concept means that it will take from the start tag to the end tag. For example, <div>...</div>, <p>..</p> and so on. But I am testing and writing the code for it, it is corrected for the correct HTML format file. If the HTML format is wrong such as the start tag includes but don't the end tag, the code shows the wrong answer and error. So how to handle these coding and what tags are only used for the content extraction?Following
- Mustapha Bouakkaz added an answer:What is the difference between Hadoop and Data Warehouse?I have read a couple of articles which are trying to sell the idea that the organization should basically choose between either implementing Hadoop (which is a powerful tool when it comes to unstructured and complex datasets) or implementing Data Warehouse (which is a powerful tool when it comes to structured datasets). But my question is, can´t they actually go along, since Big Data is about both structured and unstructured data?
The second one include the first oneFollowing

I will be monitoring, collecting, and analyzing the data of a Facebook page (posts, comments, likes, shares) and a Twitter profile (tweets, retweets, mentions, and public tweets containing one/two keywords only). Any suggestions would be great. Also, what mining techniques do you recommend? I'm thinking sentiment analysis and would like to use one or two more techniques. What techniques do you recommend?
Thanksthe easiest is GNIP, http://gnip.com/
note that you may have to pay but it may be worth it due to its simplicity (if you dont program that is !!Following
- Ian Kennedy added an answer:Can a Probabilistic timed automaton be used to model the underlying network in query routing?The network for routing the query is based on Markov process. If we want to model the time taken to answer a query , is Probabilistic timed automaton a better model?A stochastic queue would be indicated. Look up queueing theory. Start here: "http://en.wikipedia.org/wiki/Queueing_theory". If you wanted to use a number of probabilistic timed automatons, you would then have the complexity of having to build in the appropriate statistical properties.Following

- Fotis Kokkoras added an answer:Data mining and web content miningHow to data mining algorithms be implemented for web content mining?The web content extraction is a task applied to web pages, not to databases. You are scraping unstructured data from the web, you put them in structured storage (databases) and then apply data mining algorithms to them. That's the order.Following
- Pedro L Galindo added an answer:Is there a useful data set in web page classification field?I'm looking for a beneficial data set for web page classification application. Do you know a good data set?You can do it in the opposite way. I mean, Web directories, such as those provided by Yahoo! and the dmoz Open Directory Project provide an efficient way to browse for information within a predefined set of categories. You could navigate trough these web directories, store the links in these pages, and try to recover its corresponding category from its contents.Following

- Andras Kornai added an answer:Chinese textmining softwareDoes anybody know of any useable textmining software programs that do topic modeling and also cover Chinese as a language? This seems harder to find that I had thought. I found things like FudanNLP - (http://code.google.com/p/fudannlp/) and Ictclas (http://www.ictclas.org/ictclas_download.aspx), neither of which I have been able to make work so far. Pingar (http://apidemo.pingar.com/AnalyzeDocument.aspx) doesn't seem to have topic extraction. Mallet does seem to have a Chinese module and does have topic modeling, but I have yet to figure that one out too. Does anybody have any other suggestions?Have you considered commercial software vendors like Basis Tech?Following

About Web Content Extraction
Content extraction is the process of identifying the Main Content and/or removing the additional items, such as advertisements, navigation bars, design elements or legal disclaimers. The rapid growth of text based information on the Web and various applications making use of this data motivates the need for efficient and effective methods to identify and separate the Main Content (MC) from the additional content items.
