he attachment type allows to index different “attachment” type field (encoded as base64), for example, microsoft office formats, open document formats, ePub, HTML, and so on (full list can be found here).

This tutorial will walk you through basic attachment type setup and use in search including highighting. (How to use elasticsearch to index PDFs and other file types.)

The Apache Tika™ toolkit detects and extracts metadata and structured text content from various documents using existing parser libraries.

PDFMiner is a tool for extracting information from PDF documents. Unlike other PDF-related tools, it focuses entirely on getting and analyzing text data. PDFMiner allows one to obtain the exact location of text in a page, as well as other information such as fonts or lines. It includes a PDF converter that can transform PDF files into other text formats (such as HTML). It has an extensible PDF parser that can be used for other purposes than text analysis.

XHTML2PDF is a converter for HTML/XHTML and CSS to PDF and a Python package.

In MPI video, a viewer could view an event from multiple perspectives, even based on the contents of the events.

In this paper we take a rather unusual, non-technical approach and investigate object-oriented programming and the prototype-based programming field from a purely philosophical viewpoint.

Some .pdf forms allow you to fill them in, but most don't. In the old days your choices were a pen or a typewriter--neither particularly appetizing. Now you can use Gimp to fill in the forms.

Eliciting the native music information strategies employed by people searching for popular music.

Advanced techniques are necessary to help users navigate in large music catalogs... there is still a long way to go... in particular concerning the nature of the metadata and similarity relations extracted.

In order for MIR to succeed, researchers need to work with real user communities and develop research resources such as reference music collections.

An identification mechanism that exploits the information found in music audio filenames.

A knowledge-based approach to learning rules for named-entity extraction from unstructured Web text.

Our research explores approaches to the namematching problem that improve accuracy, by combining multiple string similarity methods that capture different notions of similarity to adapt to a specific domain.

The SemanticWeb seeks integrate data from many different sources. Since different sources often use different names for the same object, we need to map between these names.

Integrating and composing web services from different providers requires a solution for the problem of different providers using different names for the same object.

Methods for unsupervised learning of text profiles for music from unstructured text obtained from the web.

The beauty of this approach lies in the possibility to access so-called cultural metadata that is the agglomeration of several independent--originally subjective--perspectives about music.

A scalable disambiguation algorithm that prunes irrelevant concepts and allows relevant ones to associate with documents and participate in query generation.

A music retrieval method which retrieves songs based on the user's musical preferences. Since music preferences are expected to be highly ambiguous, relevance feedback methods are used to improve performance.

Singingfish.com uses MPEG-7 description schemes to model the metadata characteristics of Internet streaming media.

This special issue of Computers and the Humanities addresses the challenges and opportunities in designing, building, and using digital image collections.
