Consider the concept combination ??pet human??. Human subjects readily ascribe the property ??slave?? to this combination when it is not an associate ascribed to ??pet??, or ??human?? in isolation. Such emergent associations sometimes have a creative character and cognitive science is largely silent about how we produce them. Departing from a three-level model of cognition, this presentation will...
Content-based image retrieval (CBIR) has been an active research area for the last two decades and much progress has been made in that time. However, there are still many challenges to be overcome and in this paper we highlight some of these together with some approaches that we have developed to address these problems. In particular, we focus on the issues of colour (or more precise colour variance),...
This paper attempts to establish the case for the use of SNA to uncover the invisible patterns and structures of academic community. An overview of the possible application areas and methods and metrics of SNA are also provided. A case of the structure and characteristics of the digital library community is provided to illustrate. The digital library community exhibits the small world phenomenon and...
This paper presents the results of the preliminary evaluation of the accurateness of the automated marking implemented by an IR-based marking engine on free-response mathematics solutions. The development of the marking engine is based on adaptation of techniques in text retrieval process. The engine incorporates our own similarity measure which models a mathematical expression as a multiset of mathematical...
Over the past decades, computer revolution has opened up many possibilities for new field of investigation. With greater accessibility to information and lowering cost of powerful computers, this has spawned new efforts towards understanding complex tasks. Lexicon in particular has long been recognized as interesting and challenging because of its complexness. It is the knowledge of individual words...
Centre-based clustering is among the most applicable method for partitioning objects into homogenous groups. This paper presents two Centre-based clustering; K-Means and K-Modes algorithms to investigate and evaluate the clustering results of Y-STR data. The main goal of this paper is to compare the accuracy of clustering Y-STR results for different types of data: numerical and categorical data. The...
User Interface (UI) is an interaction medium of human and computers for performing different tasks. It is also referred to as Human Computer Interaction (HCI), a discipline under Social Science and Behavioral Science that deals with human factors. How well human can interact with the computers determines how well users are able to communicate and perform their desired tasks. In a collaborative environment,...
Video retrieval is one of the most famous issues in multimedia research. Users express their needs in terms of queries and expect to retrieve most relevant answers. This task is becoming harder due to large amount of video archives including broadcast news, documentary videos, movies and particularly internet which let users to search and share videos all over the world. Retrieving videos is challenging...
Nowadays, there is a vast amount of information available in the internet. The useful data must be captured and stored for future purposes. One of the major unsolved problems in the information technology (IT) industry is the management of unstructured data. The unstructured data such as multimedia files, documents, spreadsheets, news, emails, memorandums, reports and web pages are difficult to capture...
This paper examines the performance of Addaall stemmers for Arabic news of al-Jazeera. The morphological variation of Arabic word is a factor that affects Arabic information retrieval performance. Many morphological stemmers were developed to improve Arabic information retrieval such as Buckwalter, Khoja stemmers. Addaall stemmer is among the recent developments pertaining to the enhancement of the...
The availability of online GIS (Geographic Information Systems) maps has provided a new source of spatial information to tourists. However these maps have yet to be evaluated of their effectiveness. This has challenged scholars to further investigate methods of evaluating geographic information retrieval. Therefore the main objective of this paper is to evaluate the effectiveness of GoogleMap as one...
Fast image transmission is important in real time applications. However, high quality images need significant transmission time. In this paper we show that it is possible to send low resolution images with high transmission rate and then reconstruct them at destination to obtain high resolution images. First, original images are down-sampled to reduce their size. Then, these low resolution images...
Researchers have largely focused on analyzing citation links from one scholarly work to another. Such citing sentences are an important part of the narrative in a research article. If we can automatically identify such sentences, we can devise an editor that helps suggest when a particular piece of text needs to be backed up with a citation or not. In this paper, we propose a method for identifying...
On the one hand, information storage and retrieval through the Internet has made spectacular progress. On the other hand, practical searching for information still confronts us with retrieval systems that are far from perfect. The purpose of this contribution is to clarify the practical state of the art of finding information through image web search systems in a particular subject domain and to derive...
A new shape descriptor called the Invariant Generalised Ridgelet-Fourier is defined for the application of Content-based Image Retrieval (CBIR). The proposed spectral-based method is invariant to rotation, scaling, and translation (RST) as well as able to handle images of arbitrary size. The implementation of Ridgelet transform on the ellipse containing the shape and the normalisation of the Radon...
