WEB DATA MINING TO DETECT ONLINE SPREAD OF TERRORISM
|Terrorism has grown its roots quite deep in certain parts of the world. With increasing terrorist activities it has become important to curb terrorism and stop its spread before a certain time. So as identified internet is a major source of spreading terrorism through speeches and videos. Terrorist organizations use internet to brain wash individuals and also promote terrorist activities through provocative web pages that inspire helpless people to join terrorist organizations.
So here we propose an efficient web data mining system to detect such web properties and flag them automatically for human review. Data mining is a technique used to mine out patterns of useful data from large data sets and make the most use of obtained results. Data mining as well as web mining are used together at times for efficient system development.
Web mining also consists of text mining methodologies that allow us to scan and extract useful content from unstructured data. Text mining allows us to detect patterns, keywords and relevant information in unstructured texts. Both Web mining and data mining systems are widely used for mining from text.
Data mining algorithms are efficient at manipulating organized data sets, while web mining algorithms are widely used to scan and mine from unorganized and unstructured web pages and text data available on the internet. Websites created in various platforms have different data structures and are difficult to read for a single algorithm.
Since it is not feasible to build a different algorithm to suit various web technology we need to use efficient web mining algorithms to mine this huge amount of web data. Web pages are made up of HTML (Hyper text markup language) In various arrangements and have images, videos etc intermixed on a single web page. So we here propose to use smartly designed web mining algorithms to mine textual information on web pages and detect their relevancy to terrorism. In this way we may judge web pages and check if they may be promoting terrorism. This system proves useful in anti terrorism sectors and even search engines to classify web pages into the category. Their relevancy to the field help classify and sort them appropriately and flag them for human review.
