 Hello to everyone and thank you for your time. I've allowed 30 minutes for the presentation and 15 minutes for the discussion. If we don't have enough time for all the questions raised, we'll collate them at the end and email the answers. If you think of any questions as we go along, do enter them in the chat box and we'll come to them after the presentation, or I should say the question box. Okay, all right. I just want to say a few words first about how we came to do the project that resulted in the Thesaurus Management Interface. The CESTA ELF project, prior to 2012, the UK Data Archive managed two Thesauri in two separate databases, their HACET and ELFST. Funding from the ESRC for the project extends from October 2012 to September 2017 to undertake the Sauri alignment, which is completed. Update and revise the Sauri and streamline their management, which is in process, and make compliant as far as possible with new international Thesaurus guidelines, the ISO guidelines, and create the SCOS version of both the Sauri to make available for linked data, which is completed. Okay, SCOS HACET funding from GISC extended from June 2012 to March 2013 to apply SCOS to our HACET Thesaurus, applying SCOS to HACET has meant that our Thesaurus is more widely available and more usable. SCOS encodes the Sauri in a systemized way using RDF to make their structures comparable and to facilitate interaction, and SCOS has now been applied to ELFST. Okay, the majority of you are familiar with HACET, so you want to be alerted to any major changes in the new interface. For the few that are new to HACET, if you've not already had an opportunity to read the HACET guide, this is a good place to start. You can see on the main page. Okay, first, we no longer refer to synonyms. You can see from the old screen that we used to refer to terms and synonyms. We no longer refer to synonyms and primarily refer to concepts rather than terms. Okay, so the Suggest to Change screens now in the new interface you'll see have Suggest New Concept buttons and Suggest Concept Deletion buttons. So a few comments on the use of the word concept is helpful. SCOS has been applied to HACET, so we refer to SCOS concepts now rather than preferred terms. A SCOS concept is defined within a hierarchical scheme. I won't go into that in detail, but here's a useful link on Wikipedia. The application of SCOS to HACET was a critical step in the alignment of HACET and ELST. Okay, the other changes to synonyms are now used for terms. You can see the old SCOS screen had synonyms for economics, political economy. Now the current version we have used for, you can see there, it's a better label now as we've always used the field as if it was a useful field. For example, health and wellbeing terms were never synonyms. Another change is that polyhierarchies are now displayed so that we know exactly where they exist. So this is an example of the new technology and innovation hierarchy. Okay, just to begin with indexing with HACET, the above changes have no effect on the way we've used HACET in the past. The hierarchical structure still provides a range of associated terms to denote a level of specificity, usually BTs or NTs, and selecting the level is much like choosing a point on the scale. Just to illustrate the new hierarchy again, the science of technology. You can see the scale down to mobile phones and smartphones. Okay, the flow chart from the ISA standards for selecting indexed terms provides a helpful guide to follow the process of identifying the need for a new suggestion for the source. So we'll just start with that. So the flow chart will begin, examine the document, and identify significant concepts and consider the first concept. Does the thesaurus contain the term denoting the concept? We need to go to HACET then to find out. Or you will see actually, I should revise that and say you'll see it on your screen, your input screen. So to search HACET, either click on the toolbar link or enter the term in the search box. The quickest route is to use the search box. The link on the toolbar provides you with an option to browse the whole thesaurus if you do not have a specific term in mind. Okay, so we enter a term. In this case, I've put in child health. So there's no results found. You can either clear the screen and try an alternate term or select the tree view for an appropriate hierarchy. At this point, I could try the live screen. I'll just see how we go. Is that showing? No, it's not showing. Yeah, okay. I'll stay with this screen for the moment. We go on again. Does the thesaurus contain a term or can the term... No, it doesn't. So can the term be expressed unambiguously by a combination of other preferred terms? So in this case, if we go in via the tree view, I'll just see if I can change my screen now to show my other monitor. I've got the live screen going now. So I'll just put in our term. Okay. And we go to the search. There's no results found. We can go to the tree view then and go down to health. Click on health. And we get the screen that I have on my slide. So I'll just go back to my slides now. Okay. Yeah. Okay. All right. Okay. So from here, we can go to the visual graph, which is an excellent way of exploring concepts. Apologies again. I'm just having a little trouble moving the screen. Okay. Here I am. All right. So if we go to the visual graph, click on the full screen to see terms clearly. From here, so I'll put on the full screen. From here, we can explore related terms. So I have health. I click on related terms. And I can choose whichever might seem appropriate. I could perhaps go to health services. If we're looking at child health, for instance. At any point of the search, there's an option to return to the view concept page by just resetting the graph. I'll try that in a minute. But here we are in health services. We can look further for related terms there. And again, by clicking on the magnifying glass, we can return to the view concept page. Here I can go to that particular view concept page. But if I go back to my, no, sorry. That's not helping there. If I've gone down that track, where was I? Health services. I just wanted to show you the reset graph button that will return you to the original point of the display. Go back to my slides now. That's right. Okay. The flowchart of indexing decisions using the thesaurus will take that a step further. If the concept can be expressed by a combination of other preferred terms that we might have found either through the view concept screen or the visual graph, consider each term and consider the associated terms. I've just done a quick example here of a particular study. I won't go into that in great detail. It's just there for reference with a question and a combination of keywords that we might choose to use and that have been used to index it. So it's what we mean to form a screen by associated terms and the thesaurus. Okay. If we can't find a combination of terms, then we'll go on to the hazard suggestion screen which you'll find on the toolbar. Click on this screen which will take you to a registration page enter your University of Essex login and you'll be immediately taken to a suggestion page where you can check if your suggestion has already been made. Use the search box there to enter your term and it'll tell you either there's no suggestions found or you might find that your suggestion has already been entered. If your suggestion has been made, then add your comment. At the moment we've got this edit button to add your comment to. Just be aware that unlike the formative procedure for suggestions, any comments can be read by all registered users. Okay. There's two types of hazard suggestions. First is just a term suggestion as we've been using in the example of child health or editor term suggestion. It's equally important to suggest a change to improve the currency of the source as it is to suggest a new term. So on your box you'll have, I'll show you on the next screen, you can either enter the new term or you can enter a comment such as this term is out of date and needs a new scope note to the type of comment. Studies use this term rather than the existing hazard keyword. Okay. Once we've entered our term, if the term or edit hasn't been suggested, then click on the suggested change link which is to the left of your screen. An example of an edit change we're aware of in the source and we'll be attending to shortly is the issue of same-sex marriage. At the moment it's a use for in the civil partnerships and since the law has been, is now been introduced in the UK, the same-sex marriage will want to make a change there but that type of suggestion is really helpful. Okay. On the suggestion page, enter a suggestion title that summarises the issue. This is a mandatory field. I just gave examples before of either the term which we've got there of child health or you can make it longer, you know, the scope note is out of date, et cetera that we've just discussed. The reason for suggestion is important information for us. It should include a reference to the data to be indexed and a link to the study guide which is particularly helpful. I think everyone's been doing that in the past when they've sent the JIRA request through. It's proved to be so hopeful. And once the suggestion title and reason for suggestion fields have been completed, click on the suggest new concept button which is here. This will open and this will extend the options extend the screen. Enter as much information as you have and click on the save button there. The cancel button will refresh these fields but not delete the information entered above the suggest new concept button. If you enter a border term in that list, it's not a mandatory field but your suggestion for a preferred term will be shown in the position that will occupy in the hierarchy to the left. So you'll immediately see it's in alphabetical order and child health will be entered here. Once you've saved the suggest new concept information, the field summary of suggested changes will be automatically filled above. You can continue to add suggestions in this manner. It was designed specifically so that a number of related suggestions, a number of steps to the suggestion can be grouped together. Use the multiple suggestion facility only for related issues. We'd recommend as unrelated suggestions will be lost in the suggestions index that we looked at in the slides above. Once your suggestion information is complete, click on the submit suggestion button. The cancel suggestion will clear all the fields. Okay, just a quick comment about future work. What we're aiming to do in the project for the remainder of the time is to review hierarchical structure and review the use of polyhierarchies, updating concepts, so we're aiming to remove redundant terms and review currency of terms and review our scope notes. And here's suggestions for edit to hassle that will play an important role in this work. Okay, thank you all and the new hazard can be found at this URL. And we'd invite you now to try hazard suggestions. And if it's not intuitive, we'll be happy to schedule another webinar. Okay, these are just some references that I've referred to in the slides. And now open for any questions.
