Due to the exponential growth of Internet users and traffic, information seekers depend highly on search engines extract relevant information. accessibility a large amount textual, audio, video etc., contents, responsibility has increased. The engine provides concerning their query, based content, link structure, etc. However, it does not guarantee correctness performance is dependent upon rank...

Recently a few systems for automatically solving math word problems have reported promising results. However, the datasets used for evaluation have limitations in both scale and diversity. In this paper, we build a large-scale dataset which is more than 9 times the size of previous ones, and contains many more problem types. Problems in the dataset are semiautomatically obtained from community ...

In this paper, we explore the use of new page segmentation algorithm using both visual and structural mark-up (,) to partition web pages into blocks and investigate how to take advantage of block-level evidence to improve retrieval performance in the web. We propose a new ranking function that combines content and link rank based on propagation of scores over links on block-to-page grap...

In such a scenario it is the duty of service provider to provide proper, relevant and quality information to the internet user against their query submitted to the search engine. It is a challenge for service provider to provide proper, relevant and quality information to the internet user by using the we...

Ordering search results collected from multiple sources is a challenge to metasearch engines. We present an “autonomous” ranking method, meaning one that does not depend on the individual rankings returned by the engines participating in the search. Instead, it applies our TOPIC method for evaluating the reputation of a web page on a topic [7, 6] to the problem of ranking the results to a query...

In the first year of the TREC Micro Blog track, our participation has focused on building from scratch an IR system based on the Whoosh IR library. Though the design of our system (CipCipPy) is pretty standard it includes three ad-hoc solutions for the track: (i) a dedicated indexing function for hashtags that automatically recognizes the distinct words composing an hashtag, (ii) expansion of t...

filtering of web pages with inappropriate contents is one of the major issues in the field of intelligent network's security. having a good intelligent filtering method with high accuracy and speed is needed for any country in order to control users' access to the web. so, it has been considered by many researchers. presenting web pages in an understandable way by machines is one of the most im...

Day by day the growth of the World Wide Web is increasing very rapidly. One of the research quotes "There are more than 11. 3 billion web pages in the World Wide Web". Search engines help the user to surf the web. Due to the vast number of web pages it is highly impossible for the user to retrieve the apt web page he needs. Thus, Web search ranking algorithms play an important role in...
