Some studies on a probabilistic framework for finding object-oriented information in unstructured data
... probabilistic framework for finding object-oriented information in unstructured data [13] [14]. To deal with this problem more efficient, we have proposed an approach for generating snippet for this system ... crucial for Internet users to obtain the desired information in an efficient and direct manner. Currently, there is a lot of information available in structured format on the web. For example, ... the format of the number in standard and Vietnamese format. For example, “123456.78” in standard format is “123,456.78” which in Vietnamese format is “123.456,78”. We use regular expression for...

A new algorithm for enumeration of minimum cutsets of graph by branch addition
... problem can be solved easily. For this approach, above algorithm should be changed as follows: 1. Algorithm should start with an output node. 2. The node set made for minimum cutset enumeration, ... other algorithms should be searched in such cases. Some of these algorithms, which are based on finding minimum paths, need a large size of memory and more computation time. Thus, these algorithms ... [4]. Recursive algorithm to enumerate minimum cutset of a directed graph, using dynamic programming technique has been used in [5]. An efficient algorithm is also presented for undirected...
