Katsir: A Framework for Harvesting Digital Libraries on the Web

The information era has brought with it the wellknown problem of \u27Information Explosion\u27. There are many and varied search engines on the Internet but it is still hard to locate and concentrate only on materials relevant to a specific task. Digital libraries, on the other hand, provide better services for focused discovery of relevant Web resources. However, digital libraries have been much less researched and implemented than search engines. The \u27Katsir/Harvest\u27 project laid the ground for our understanding that a new paradigm should to be developed - the Harvested Digital Library (HDL). The contribution of this article is in presenting a new framework and harvesting model for constructing HDLs. The open harvesting architecture proposed here uses advanced information retrieval tools and provides a set of integrated DL services to its users. This model and architecture are discussed throughout the article, including description of the implemented Katsir system and discussion of future research directions. The future DLs will be knowledge rich in the sense that each DL contains relevant meta-information on its domain and employs advanced knowledge management techniques

Priority questions and horizon scanning for conservation: A comparative study

Several projects aimed at identifying priority issues for conservation with high relevance to policy have recently been completed in several countries. Two major types of projects have been undertaken, aimed at identifying (i) policy-relevant questions most imperative to conservation and (ii) horizon scanning topics, defined as emerging issues that are expected to have substantial implications for biodiversity conservation and policy in the future. Here, we provide the first overview of the outcomes of biodiversity and conservation-oriented projects recently completed around the world using this framework. We also include the results of the first questions and horizon scanning project completed for a Mediterranean country. Overall, the outcomes of the different projects undertaken (at the global scale, in the UK, US, Canada, Switzerland and in Israel) were strongly correlated in terms of the proportion of questions and/or horizon scanning topics selected when comparing different topic areas. However, some major differences were found across regions. There was large variation among regions in the percentage of proactive (i.e. action and response oriented) versus descriptive (non-response oriented) priority questions and in the emphasis given to sociopolitical issues. Substantial differences were also found when comparing outcomes of priority questions versus horizon scanning projects undertaken for the same region. For example, issues related to climate change, human demography and marine ecosystems received higher priority as horizon scanning topics, while ecosystem services were more emphasized as current priority questions. We suggest that future initiatives aimed at identifying priority conservation questions and horizon scanning topics should allow simultaneous identification of both current and future priority issues, as presented here for the first time. We propose that further emphasis on social-political issues should be explicitly integrated into future related projects

The number and percentage of priority questions that deal with each of the major categories examined in the projects.

<p>These include: climate change; socio-political issues or policy; human demographic issues (population size etc.); human related systems (including agriculture, human settlements, human-dominated landscapes, infrastructure etc.); freshwater systems (e.g., freshwater, rivers, water market etc.); marine systems; ecosystem services; cross-boundary issues (political boundaries, neighboring countries etc.); descriptive questions: those that describe and study problem/threat; proactive questions: questions that deal with solutions and action to address problem. The table provides the number and percentage of questions in each category. A question can assigned to none, a single or more than one category.</p
