The major challenge in wireless sensor networks is to decrease energy consumption and to increase the throughput of sensor node to enhance the lifetime of sensor network. The routing protocols have great impact on the lifetime of sensor network. Mainly the data packet delivery ratio and average energy consumption are examined as the performance metrics. Simulation results show that proposed algorithm performs better than EQSR (Energy Efficient and QOS aware multipath routing) and comparison is performed in term of data packet delivery ratio and energy consumption. General TermsWireless sensor network, Two-pass Algorithm, Energy Efficient and QoS multipath routing (EQSR)

<span lang="EN-US">The emergence of the Web technology generated a massive amount of raw data by enabling Internet users to post their opinions, comments, and reviews on the web. To extract useful information from this raw data can be a very challenging task. Search engines play a critical role in these circumstances. User queries are becoming main issues for the search engines. Therefore a preprocessing operation is essential. In this paper, we present a framework for natural language preprocessing for efficient data retrieval and some of the required processing for effective retrieval such as elongated word handling, stop word removal, stemming, etc. This manuscript starts by building a manually annotated dataset and then takes the reader through the detailed steps of process. Experiments are conducted for special stages of this process to examine the accuracy of the system.</span>
