An Approach to Design a Compiler in Context of Lexical Analyzer (Scanner) and Parser Generation (Parser) Followed by Non-optimized Intermediate Code Generation using Compiler Construction Tools Partha Ghosh* Department of Computer Science & Engineering, Govt. College of Engineering & Ceramic Technology, Kolkata, India

Abstract It is very tedious and lengthy task to write a compiler. To realize the various phases of compilers we can use some specific tools. These tools are called compiler construction tools. Furthermore, we call it as compiler-compiler, compiler-generators, or translator writing system. A mixture of compiler building tools are Scanner generator —it generates lexical analyzers. The patterns specified to these generators are in the type of regular expressions. The LINUX has utility for a scanner generator called LEX. The specification given to the LEX consists of regular expressions for representing various tokens. Parser generators — these produce the syntax analyzer. The specification given to these generators is given in the form of CFG. Typically LINUX has a tool called YACC, which is a parser generator. Syntax-directed translation engines — in this tool the parse tree is scanned fully to generate an intermediate code. The translation is done for each node of the tree.

An Implementation of Extracting Data and Mining Extracted Data from Web Pages Dhanashri Sandbhor*, Archana Jadhav, Govind Kumar Dubey, Sonali Pawade, Rupesh Dhole Information Technology Department, Rajarshi Shahu College of Engineering, Tathawade, Pune-033, Pune University, Maharashtra, India

Abstract Web contains various information of particular object, which could be relevant as well as non-relevant are called as data records. It is necessary to extract relevant information from web pages. Web data extraction is the system which is used for extracting data from various web pages. Data present on web pages are in un-structured format. In the process of data extraction, we convert un-structured data into structured format. This paper contains web data extraction system, stages of making a mashup and the data mining concept for data clustering. Mashup is the process which provides functionality such as data retrieval, data source modeling, data cleaning/filtering, data integration, and data visualization. We use “Xtractorz” system for data extraction and mashup for data records. By using data mining, we analyze data from different sources and using text mining we cluster all the information. And we also use those data for providing value added services Keywords: Web, data, mashup, data clustering

Abstract Traditional IP network infrastructure is merely static, rather than flexible. Due to the advent of Cloud technologies, future networks of machine-to-machine (M2M)/Internet of Things (IoT) and the mobile devices generating Big Data, it has become very difficult for network managers to configure and monitor the everchanging network dynamically. Recently, the concept of Software-Defined Network (SDN), which allows us to administer and configure a network in a centralized and programmable manner, has gathered network engineers’ and researchers’ attention rapidly. OpenFlow has opened the door for network management in a more controlled way. Though OpenFlow controllers provide a lot of raw data collected from the underlying flows, it is still difficult for network managers to do analysis of that Big Data and take better decisions for the network. This research aims to realize a visualization software that facilitates the network managers to analyze the flow data in a more user-friendly way. The proposed tool helps us to visually identify selected flows from all lists of flows (i.e., Flowspace) and to monitor the status of selected flows through application-specific interactive visual representations.
