Verifying Hadith Correctness in Islamic Web Pages using Information Retrieval Techniques

Certain types of web information need to be verified for correctness once being posted on the web (i. e. the information has a reference that cannot be tampered with). Such these types of information need systems in order to verify and assure their correctness. "The Hadith"; which is the sayings of Prophet Mohammad is an example of these types of information. Hadith in Islam is a very important tool to understand Qur'an, and in matter of Islamic law. This paper presents a reliable method to extract Hadith text from web pages, in order to find out the degree of correctness for each one; by looking it up in Sheikh AlAlbani Hadith Database (correct series and weak series) which contains 17000+Hadeeth texts and their degrees of correctness according to Sheikh Al-Albani studies. The proposed approach uses positional index built over the Sheikh Al-Albani Hadith Database (SAHDB) and extracts Hadith terms as queries from the passed web page, and execute these queries over SAHDB index.
