In this paper, an approach for storing Markov tree, used in various versions of PPM model while predicting next web-page is proposed. Markov tree requires huge amount of memory. This problem is solved using cellular automata which is considered as a fast and inexpensive mechanism. The proposed technique utilizes non-linear single cycle multiple attractor cellular automata (SMACA) which replaces Markov tree for minimizing the memory requirement.

Search for any topic or a word using web search engine depends on its ranking mechanism. Generally, search engine sorts through the millions of web pages and then present the significant web-pages that match search topic of the user. These matches will be further ranked, so that the most relevant ones come first. This paper proposes an alternate way to rank hyper-linked web page through analysis of link structure. This link structure is stored in an efficient way to minimize the storage space using Galois Extension Field GF (2 P ).

In this paper we describe a technique for automatic construction of ontology, a semantic representation of a conceptualization, for any domain, organization or enterprise whose web site is existent with quiet a big mine of information. An user interactive system is developed with the help of which any organization, which has a web site to maintain data, but has no corresponding semantic mark up, can automatically construct the ontology and further use that to model domain knowledge and make use of various semantic web applications like semantic web search engine etc. The automated construction of ontology will facilitate further the growth, popularity and usage of the semantic web and semantic web technologies as well as serve as a basis for artificial intelligence reasoning.

An extremely large number of web pages in the Internet contain free texts in natural language that are only read by human beings. To be understood by machines, these pages should be annotated with semantic markups. Manually annotating large number of pages is an arduous work. This has made automatic semantic annotation an urgent challenge. In this paper, we propose machine learning based automatic annotation approach. This approach can be trained for different domains and requires nearly no manual rules.

The web has grown in leaps and bounce in the last decade. The size of the web has become so large that it has become very difficult to find out the necessary information from the web. Search engines help us in our quest of finding the required information on the web. These search engines over the years have also developed themselves in a grand manner. With the advent of ontology based search engine, has only helped the cause. Ontology based search engines are transforming the whole idea of searching into a new league of its own. In this paper we propose a novel approach for proper construction and searching ontology. This proposition of ours will help in the development of a very well organized ontology which in tern will help us in searching the web in a very useful and organized manner. Thus reducing the unwanted search results.

A domain specific web search engine is a search engine which replies to domain specific user queries. The crawler in a domain specific search engine must crawl through the domain specific web pages in the World Wide web (WWW). For a crawler it is not an easy task to download the domain specific web pages. Ontology can play a vital role in this context. Our focus will be to identify web pages for a particular domain in WWW.

Both symmetric and asymmetric key algorithms are used to secure a network. Asymmetric key approach involves greater time complexity and hence prone to higher power consumption. Symmetric key cryptography, on the other hand, involves a key exchange phase. In this paper, we propose an authentication technique for new nodes to an ad-hoc network that would also extract the advantages of both symmetric and asymmetric key cryptography while avoiding the adversities. In the proposed collaborative technique, the new node is not only authenticated, but the request-reply messages have been used to generate a secret key at the two ends. The proposed algorithm estimates the distance of a node X from the power loss of a message from X. Both the sender and the receiver separately compute the same secret key based on this distance. The proposed algorithm does not use GPS and identifies location of nodes by distance and direction only.

Search for a web-page using Crawler based Search Engine depends on its Ranking Mechanism. Search Engine sorts through millions of web-pages and present the significant web-pages through Ranking method. A new approach is proposed here adopting Cellular Automata.
