Haystack (MIT Project)
Haystack is a project at the Massachusetts Institute of Technology to research and develop several applications around personal information management and the Semantic Web. The most notable of those applications is the Haystack client, a research personal information manager (PIM) and one of the first to be based on semantic desktop technologies. The Haystack client is published as open source software under the BSD license. Similar to the Chandler PIM, the Haystack system unifies handling different types of unstructured information. This information has a common representation in RDF that is presented to users in a configurable human-readable way. Adenine Haystack was developed in the RDF-aware dynamic language Adenine which was created for the project. The language was named after the nuclease adenine and is a scripting language that is cross-platform. It is the perhaps the earliest example of a homoiconic general graph (rather than list/tree) programming language. A subst ...

Massachusetts Institute Of Technology
The Massachusetts Institute of Technology (MIT) is a Private university, private research university in Cambridge, Massachusetts, United States. Established in 1861, MIT has played a significant role in the development of many areas of modern technology and science. In response to the increasing Technological and industrial history of the United States, industrialization of the United States, William Barton Rogers organized a school in Boston to create "useful knowledge." Initially funded by a land-grant universities, federal land grant, the institute adopted a Polytechnic, polytechnic model that stressed laboratory instruction in applied science and engineering. MIT moved from Boston to Cambridge in 1916 and grew rapidly through collaboration with private industry, military branches, and new federal basic research agencies, the formation of which was influenced by MIT faculty like Vannevar Bush. In the late twentieth century, MIT became a leading center for research in compu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Lisp (programming Language)
Lisp (historically LISP, an abbreviation of "list processing") is a family of programming languages with a long history and a distinctive, fully parenthesized prefix notation. Originally specified in the late 1950s, it is the second-oldest high-level programming language still in common use, after Fortran. Lisp has changed since its early days, and many dialects have existed over its history. Today, the best-known general-purpose Lisp dialects are Common Lisp, Scheme, Racket, and Clojure. Lisp was originally created as a practical mathematical notation for computer programs, influenced by (though not originally derived from) the notation of Alonzo Church's lambda calculus. It quickly became a favored programming language for artificial intelligence (AI) research. As one of the earliest programming languages, Lisp pioneered many ideas in computer science, including tree data structures, automatic storage management, dynamic typing, conditionals, higher-order function ...

Education Karger received a Bachelor of Arts degree from Harvard University and a PhD in computer science from Stanford University. Research Karger's work in algorithms has focused on applications of randomization to optimization problems and led to significant progress on several core problems. He is responsible for Karger's algorithm, a Monte Carlo method to compute the minimum cut of a connected graph. Karger developed the fastest minimum spanning tree algorithm to date, with Philip Klein and Robert Tarjan. They found a linear time randomized algorithm based on a combination of Borůvka's algorithm and the reverse-delete algorithm. With Ion Stoica, Robert Morris, Frans Kaashoek, and Hari Balakrishnan, he also developed Chord, one of the four original distributed ...

Personal Knowledge Base
A personal knowledge base (PKB) is an electronic tool used by an individual to express, capture, and later retrieve personal knowledge. It differs from a traditional database in that it contains subjective material particular to the owner, that others may not agree with nor care about. Importantly, a PKB consists primarily of knowledge, rather than information; in other words, it is not a collection of documents or other sources an individual has encountered, but rather an expression of the distilled knowledge the owner has extracted from those sources or from elsewhere.See also the dissertation of Max Völkel, which examined personal knowledge data models, and proposed a meta-model called "Conceptual Data Structures": The term was mentioned as early as the 1980s, but the term came to prominence in the 2000s when it was described at length in publications by computer scientist Stephen Davies and colleagues, who compared PKBs on a number of different dimensions, the most importan ...

Beagle (software)
Beagle is a search system for Linux and other Unix-like systems, enabling the user to search documents, chat logs, email and contact lists. It is not actively developed. Beagle grew out of Dashboard, an early Mono-based application for watching and presenting useful information from a user's computer. It is written in C# using Mono and uses a port of Lucene to C# called Lucene.Net as its indexer. Beagle includes a Gtk#-based user interface, and integrates with Galago for presence information. Beagle was developed and maintained by Joe Shaw with help from the open source community. Notable contributors included Jon Trowbridge, Robert Love, Nat Friedman and David Camp. Features Beagle searches the content of documents and associated metadata. Users can search for: * Applications * Archives ( zip, tar, gzip, bzip2) and their contents * Conversations (Pidgin, Kopete and IRC logs) * Documents ( AbiWord, OpenOffice.org, Microsoft Office, pdf, txt, rtf, HTML) * ...

Strigi
Strigi was a file indexing and file search framework (see desktop search) adopted by KDE SC. Strigi was initiated by Jos van den Oever. Strigi's goals are to be fast, use a small amount of RAM, and use flexible backends and plug-ins. A benchmark as of January 2007 showed that Strigi is faster and uses less memory than other search systems, but it lacks many of their features. Like most desktop search systems, Strigi can extract information from files, such as the length of an audio clip, the contents of a document, or the resolution of a picture; plugins determine what filetypes it is capable of handling. Strigi uses its own Jstream system which allows for deep indexing of files. Strigi is accessible via Konqueror, or by clicking on its icon, after adding it to KDE's Kicker or GNOME Panel. (In GNOME desktop, it is called the Deskbar applet.) The graphical user interface (GUI) is named Strigiclient. It was replaced with Recoll in KDE5 Plasma desktop environment. Features * ...

Semantic Desktop
In computer science, the semantic desktop is a collective term for ideas related to changing a computer's user interface and data handling capabilities so that data are more easily shared between different application software, applications or tasks and so that data that once could not be automatically processed by a computer could be. It also encompasses some ideas about being able to share information automatically between different people. This concept is very much related to the Semantic Web, but is distinct insofar as its main concern is the personal use of information. Problems to solve The vision of the semantic desktop can be considered as a response to the perceived problems of existing user interfaces. Metadata Without good metadata, computers cannot easily learn many commonly needed attributes about files. For example, suppose one downloads a document by a particular author on a particular subject – though the document will likely clearly indicate its subject, autho ...

Chandler (software)
Chandler is a discontinued personal information management software suite described by its developers as a "Note-to-Self Organizer" designed for personal and small-group task management and calendaring. It is free software, previously released under the GNU General Public License, and now released under the Apache License 2.0. It is inspired by a PIM from the 1980s called Lotus Agenda, notable because of its "free-form" approach to information management. Lead developer of Agenda, Mitch Kapor, was also involved in the vision and management of Chandler. Chandler consists of a cross-platform desktop application (Windows, Mac OS X, Linux), the Chandler Hub Sharing Service, Chandler Server, Chandler Quick Entry for iPhone, and Chandler Quick Entry for Android. Version 1.0 of the software was released on August 8, 2008. Chandler was developed by the Open Source Applications Foundation (''OSAF''). It is named after the mystery novelist Raymond Chandler.

SIMILE
A simile () is a type of figure of speech that directly ''compares'' two things. Similes are often contrasted with metaphors, where similes necessarily compare two things using words such as "like", "as", while metaphors often create an implicit comparison (i.e. saying something "is" something else). However, there are two schools of thought regarding the relationship between similes and metaphors. The first defines them as opposites, such that a statement cannot be both a simile and a metaphor — if it uses a comparison word such as "like" then it is a simile; if not, it is a metaphor. The second school considers metaphor to be the broader category, in which similes are a subcategory — according to which every simile is also a metaphor (but not vice-versa). These two schools reflect differing definitions and usages of the word "metaphor" and regardless of whether it encompasses similes, but both agree that similes always involve a direct comparison word such as "like" or "as". ...

Notation3
Notation3, or N3 as it is more commonly known, is a shorthand non-XML serialization of Resource Description Framework models, designed with human-readability in mind: N3 is much more compact and readable than XML RDF notation. The format is being developed by Tim Berners-Lee and others from the Semantic Web community. A formalization of the logic underlying N3 was published by Berners-Lee and others in 2008. N3 has several features that go beyond a serialization for RDF models, such as support for RDF-based rules. Turtle is a simplified, RDF-only subset of N3. Examples The following is an RDF model in standard XML notation: Tony Benn Wikipedia may be written in Notation3 like this: @prefix dc: . dc:title "Tony Benn"; dc:publisher "Wikipedia". This N3 code above would also be in valid Turtle syntax.
