ALGORITHMSEER: A SYSTEM FOR EXTRACTING AND SEARCHING
FOR ALGORITHMS IN SCHOLARLY BIG DATA
Abstract
Algorithms are usually published in scholarly articles, especially in the
computational sciences and related disciplines. The ability to automatically find
and extract these algorithms in this increasingly vast collection of scholarly
digital documents would enable algorithm indexing, searching, discovery, and
analysis. Recently, AlgorithmSeer, a search engine for algorithms, has been
investigated as part of CiteSeerX with the intent of providing a large algorithm
database. Currently, over 200,000 algorithms have been extracted from over 2
million scholarly documents. This paper proposes a novel set of scalable
techniques used by AlgorithmSeer to identify and extract algorithm
representations in a heterogeneous pool of scholarly documents. Specifically,
hybrid machine learning approaches are proposed to discover algorithm
representations. Then, techniques to extract textual metadata for each
algorithm are discussed. Finally, a demonstration version of AlgorithmSeer that
is built on Solr/Lucene open source indexing and search system is presented.
Existing System
Standard algorithms1 are usually collected and cataloged manually in
algorithm textbooks , encyclopedias (especially the ones available online such
as Wikipedia2), and websites that provide references for computer
programmers (e.g. Rosettacode.org3). We parsed Wikipedia algorithm pages

published in 2010, and found that roughly 1,765 standard algorithms were
cataloged. The National Instituteof Standards and Technology (NIST)4 also has
a dictionary of over 289 standard algorithms. While most standard algorithms
are already cataloged and made searchable, especially those in online catalogs,
newly published algorithms only appear in new articles. The explosion of newly
developed algorithms in scientific and technical documents makes it infeasible
to manually catalog these newly developed algorithms. Manually searching for
these newly published algorithms is a nontrivial task. Researchers and others
who aim to discover efficient and innovative algorithms would have to actively
search and monitor relevant new publications in their fields of study to keep
abreast of latest algorithmic developments. The problem is worse for
algorithm searchers.
Proposed System
We proposea set of hybrid techniques based on ensemble machine learning to
discover PCs and APs in scholarly documents. We find that the textual
metadata that can be directly extracted from an algorithm representation
(especially PCs), is inadequate for effective retrieval, and propose to use the
synopsis generation method, which automatically generates a comprehensive
description for a document element, and the tag-based automatic metadata
annotation technique, which automatically textually enriches metadata
records, to extract more meaningful textual information for PCs.

Conclusion
The prototype of AlgorithmSeer, a search system for algorithms in large scale
scholarly documents, along with providing an illustration of the actual demo
system. Specifically, we proposed a set of scalable machine learning based
methods to detect algorithms in scholarly documents, we discussed using the
synopsis generation and document annotation methods to extract textual
metadata for pseudo-codes, and finally we explained how algorithms are
indexed and made searchable.
