Untangling the Web: A Guide To Internet Research

[Excerpt] Untangling the Web for 2007 is the twelfth edition of a book that started as a small handout. After more than a decade of researching, reading about, using, and trying to understand the Internet, I have come to accept that it is indeed a Sisyphean task. Sometimes I feel that all I can do is to push the rock up to the top of that virtual hill, then stand back and watch as it rolls down again. The Internet—in all its glory of information and misinformation—is for all practical purposes limitless, which of course means we can never know it all, see it all, understand it all, or even imagine all it is and will be. The more we know about the Internet, the more acute is our awareness of what we do not know. The Internet emphasizes the depth of our ignorance because our knowledge can only be finite, while our ignorance must necessarily be infinite. My hope is that Untangling the Web will add to our knowledge of the Internet and the world while recognizing that the rock will always roll back down the hill at the end of the day

CHORUS Deliverable 2.1: State of the Art on Multimedia Search Engines

Based on the information provided by European projects and national initiatives related to multimedia search as well as domains experts that participated in the CHORUS Think-thanks and workshops, this document reports on the state of the art related to multimedia content search from, a technical, and socio-economic perspective. The technical perspective includes an up to date view on content based indexing and retrieval technologies, multimedia search in the context of mobile devices and peer-to-peer networks, and an overview of current evaluation and benchmark inititiatives to measure the performance of multimedia search engines. From a socio-economic perspective we inventorize the impact and legal consequences of these technical advances and point out future directions of research

Linguistic, multimodal and cultural code-meshing: Exploring adolescents’ language and literacy practices in social networking sites

This thesis will explore language and literacy practices in social networking sites (SNSs) that both draw on and expand beyond traditional principles of composition. Particularly, it will examine how adolescent participants are engaging with SNSs in ways that extend their learning and life opportunities beyond what is typically accessible in their rural province of Chiang Rai. Despite considerable research on language and literacy, there remains a limited body of research focused on adolescent literacy in Thailand and in rural contexts, such as Chiang Rai. There is also limited research in this area that provides a combined framework to account for the social, cultural, multimodal and linguistic repertoires of adolescents as materialised in their SNS practices. This thesis will draw from sociolinguistic and sociocultural theories of Systemic Functional Linguistics (SFL) and intertextuality to analyse adolescent participants’ linguistic and multimodal texts and how they shape and are shaped by a range of discourses in SNSs. However, both of these theories cannot provide a systematic account of adolescent participants’ multimodal texts in depth. Therefore, this thesis will also draw from multimodality as an analytical framework to account for participants’ multimodal texts (e.g., images, colours and layout). As key findings will demonstrate, the complexity of participants’ language and literacy practices in SNSs involves the blending of not only different languages and modes but also cultural resources (e.g., textual conventions and genres) – or what I refer to as linguistic, multimodal and cultural code-meshing practices. This study will set out a critical perspective on how such practices on SNSs are shaped by Chiang Rai adolescents to make new kinds of meanings, negotiate identities and relationships, and establish belongingness within both local and transnational SNS communities. Evidence from empirical data collected will include surveys and online observations

Digitised Newspapers – A New Eldorado for Historians?

Digitization technologies applied to historical newspapers have changed the research landscape historians were used to. An Eldorado? Despite unquestionable merits, the new digital affordance of historical newspapers also brings drawbacks and possible pitfalls which need to be carefully assessed

As Below So Above: Reconstructing the Neo-Babylonian Worldview

To add to our knowledge about a Near Eastern culture, this project examines through textual evidence how the early first millennium BCE Neo-Babylonians thought, reasoned, and wrote in order to partially reconstruct the shared, generally held worldview of the Neo-Babylonian people using the transdisciplinary approach of worldview analysis. Worldviews are what we use to think with, not what we think about. Underlying surficial cultural behaviors are deeper levels of cognition regarding how to reason, perceive the world, prioritize values, prescribe behavior, and explain all of life. Specifically, this work examines the language and logic reflected in the textual archive, believing that this is the foundational level of any worldview. I argue that one finds two related components: (1) that they were linguistically programmed to be attuned to the full context over particularities, verbal actions over agential subjects, the continuity of substances over discrete objects, the standard use of maleness over femaleness, and the affective power of spoken or written words, and (2) that they were logically programmed to prefer gradations over distinctions, functional properties over inherent attributes, radials and/or rhizomes over linearity, and relationships and/or comparisons over abstractions and algorithms. By addressing this underlying, implicit cognitive software the Neo-Babylonians used, one is better able to understand the society’s more observable and obvious religious, ethical, legal, political, and social features. This has the potential to present a more contextualized view of Neo-Babylonian civilization. Reconstructing the ancient Neo-Babylonian worldview allows scholars to compare and contrast the linguistic and logical features to other ancient nearby cultures in order to understand continuities and differences and what accounts for them. One can open a dialogue between these ancient societies at a deeper level. It demonstrates the uniqueness of Neo-Babylonia. And it provides a basis for understanding how Neo-Babylonians contributed to the roots of Western civilization and thought. Most current worldview analysis examines modern or postmodern worldviews. By examining an ancient worldview, one can begin to more clearly understand any common aspects which exist for all worldviews and any elements that exist in ancient ones which are missing from cataloging more modern worldviews. Thus, the cataloging of an ancient worldview helps to open new vistas within worldview studies. This study invites similar ones within ancient Near Eastern studies and within ancient studies in general

Semi-automated Ontology Generation for Biocuration and Semantic Search

Background: In the life sciences, the amount of literature and experimental data grows at a tremendous rate. In order to effectively access and integrate these data, biomedical ontologies – controlled, hierarchical vocabularies – are being developed. Creating and maintaining such ontologies is a difficult, labour-intensive, manual process. Many computational methods which can support ontology construction have been proposed in the past. However, good, validated systems are largely missing. Motivation: The biocuration community plays a central role in the development of ontologies. Any method that can support their efforts has the potential to have a huge impact in the life sciences. Recently, a number of semantic search engines were created that make use of biomedical ontologies for document retrieval. To transfer the technology to other knowledge domains, suitable ontologies need to be created. One area where ontologies may prove particularly useful is the search for alternative methods to animal testing, an area where comprehensive search is of special interest to determine the availability or unavailability of alternative methods. Results: The Dresden Ontology Generator for Directed Acyclic Graphs (DOG4DAG) developed in this thesis is a system which supports the creation and extension of ontologies by semi-automatically generating terms, definitions, and parent-child relations from text in PubMed, the web, and PDF repositories. The system is seamlessly integrated into OBO-Edit and Protégé, two widely used ontology editors in the life sciences. DOG4DAG generates terms by identifying statistically significant noun-phrases in text. For definitions and parent-child relations it employs pattern-based web searches. Each generation step has been systematically evaluated using manually validated benchmarks. The term generation leads to high quality terms also found in manually created ontologies. Definitions can be retrieved for up to 78% of terms, child ancestor relations for up to 54%. No other validated system exists that achieves comparable results. To improve the search for information on alternative methods to animal testing an ontology has been developed that contains 17,151 terms of which 10% were newly created and 90% were re-used from existing resources. This ontology is the core of Go3R, the first semantic search engine in this field. When a user performs a search query with Go3R, the search engine expands this request using the structure and terminology of the ontology. The machine classification employed in Go3R is capable of distinguishing documents related to alternative methods from those which are not with an F-measure of 90% on a manual benchmark. Approximately 200,000 of the 19 million documents listed in PubMed were identified as relevant, either because a specific term was contained or due to the automatic classification. The Go3R search engine is available on-line under www.Go3R.org
