3D Virtual worlds and the metaverse
ACM Computing Surveys - Tập 45 Số 3 - Trang 1-38 - 2013
John David N. Dionisio, W. G. Burns, Richard Gilbert
Moving from a set of independent virtual worlds to an integrated network of 3D virtual worlds or Metaverse rests on progress in four areas: immersive realism, ubiquity of access and identity, interoperability, and scalability. For each area, the current status and needed developments in order to achieve a functional Metaverse are described. Factors that support the formation of a viable Me...... hiện toàn bộ
Machine learning in automated text categorization
ACM Computing Surveys - Tập 34 Số 1 - Trang 1-47 - 2002
Fabrizio Sebastiani
The automated categorization (or classification) of texts into predefined categories has witnessed a booming interest in the last 10 years, due to the increased availability of documents in digital form and the ensuing need to organize them. In the research community the dominant approach to this problem is based on machine learning techniques: a general inductive process automatically bui...... hiện toàn bộ
Bidirectional associative memories
ACM Computing Surveys - Tập 45 Số 2 - Trang 1-30 - 2013
Elena Acevedo, Cornelio Yáñez-Márquéz, Antonio Acevedo
Bidirectional Associative Memories (BAM) are systems that allow to associate pairs of patterns. Once a memory has learned, patterns can be recalled in two directions. BAMs have many applications in pattern recognition and image processing. The aim of this survey is to present several models of BAM throughout time, since Kosko [1988] proposed the first model; followed by those works based o...... hiện toàn bộ
XML data clustering
ACM Computing Surveys - Tập 43 Số 4 - Trang 1-41 - 2011
Alsayed Algergawy, Marco Mesiti, Richi Nayak, Gunter Saake
In the last few years we have observed a proliferation of approaches for clustering XML documents and schemas based on their structure and content. The presence of such a huge amount of approaches is due to the different applications requiring the clustering of XML data. These applications need data in the form of similar contents, tags, paths, structures, and semantics. In this article, w...... hiện toàn bộ
Data structures and algorithms for disjoint set union problems
ACM Computing Surveys - Tập 23 Số 3 - Trang 319-344 - 1991
Zvi Galil, Giuseppe F. Italiano
Data Structures for Range Searching
ACM Computing Surveys - Tập 11 Số 4 - Trang 397-409 - 1979
Jon Bentley, Jerome H. Friedman
Các thước đo tính thú vị trong khai thác dữ liệu Dịch bởi AI
ACM Computing Surveys - Tập 38 Số 3 - Trang 9 - 2006
Liqiang Geng, Howard J. Hamilton
Các thước đo tính thú vị đóng một vai trò quan trọng trong khai thác dữ liệu, bất kể loại mẫu nào đang được khai thác. Những thước đo này nhằm mục đích chọn lọc và xếp hạng các mẫu dựa trên mức độ quan tâm tiềm năng của người dùng. Các thước đo tốt cũng cho phép giảm thiểu chi phí về thời gian và không gian trong quá trình khai thác. Bài khảo sát này xem xét các thước đo tính thú vị cho qu...... hiện toàn bộ
The interdisciplinary study of coordination
ACM Computing Surveys - Tập 26 Số 1 - Trang 87-119 - 1994
Thomas W. Malone, Kevin Crowston
This survey characterizes an emerging research area, sometimes called coordination theory , that focuses on the interdisciplinary study of coordination. Research in this area uses and extends ideas about coordination from disciplines such as computer science, organization theory, operations research, economics, linguistics, an...... hiện toàn bộ
A survey of adaptive sorting algorithms
ACM Computing Surveys - Tập 24 Số 4 - Trang 441-476 - 1992
Vladimir Estivill‐Castro, Derick Wood
The design and analysis of adaptive sorting algorithms has made important contributions to both theory and practice. The main contributions from the theoretical point of view are: the description of the complexity of a sorting algorithm not only in terms of the size of a problem instance but also in terms of the disorder of the given problem instance; the establishment of new relationships...... hiện toàn bộ
A Survey on NoSQL Stores
ACM Computing Surveys - Tập 51 Số 2 - Trang 1-43 - 2019
Ali Davoudian, Liu Chen, Mengchi Liu
Recent demands for storing and querying big data have revealed various shortcomings of traditional relational database systems. This, in turn, has led to the emergence of a new kind of complementary nonrelational data store, named as NoSQL. This survey mainly aims at elucidating the design decisions of NoSQL stores with regard to the four nonorthogonal design principles of distributed data...... hiện toàn bộ
