This is the project page for SecondString, an open-source Java-based package of approximate string-matching techniques. This code was developed by researchers at Carnegie Mellon University from the Center for Automated Learning and Discovery, the Department of Statistics, and the Center for Computer and Communications Security.
SecondString is intended primarily for researchers in information integration and other scientists. It does or will include a range of string-matching methods from a variety of communities, including statistics, artificial intelligence, information retrieval, and databases. It also includes tools for systematically evaluating performance on test data. It is not designed for use on very large data sets.
The cb2Bib is a tool for rapidly extracting unformatted, or unstandardized bibliographic references from email alerts, journal Web pages, and PDF files.

This project aims to develop an efficient rule based extractor of entries of references, located in scientific articles in English language. The application takes a pdf file or a directory of pdf and then returns an html file, containing the list of all entries with their respective title. Moreover the title of the article cited is searched through Google Web Service to get the URL that identifying the article on the web. If the URL provides on the page a Bibtex entry, this will appear in the html output under the relative entries, stolen from some typical site like citeseer, ieeexlpore etc. The application does not make search over pdf file based on images.
What would be a good way to extract headlines, dates, and authors from news articles? It seems easy to write a scraper using xpath or similar to extract this information from a single site, but I'm not sure of a more scalable solution if you're extracting from say 10,000 sites.
The Fusion PDF Image Extractor has two purposes:
To extract all of the individual images from a PDF (to gather the images from brochures etc) (limited to JPG images so far)
To extract all of the pages of a PDF as JPEG image representations of the original page
We have released a zip file containing all of the program files and the source code to do with as you please. We have also released a windows installation image for anyone not comfortable handling zip files.
