[CODE4LIB] How to measure quality of a record
Hello community, is there a way, any statistical approach, that you are aware of that let's say, allows one to have an idea of how complete a record is, or what are the actions you take in order to have an idea of the quality of a record, and eventually a database? Thank you in advance
Re: [CODE4LIB] Library Hours
I'm curious, Karen, Ethan or anyone else, do you know of any examples of libraries that have implemented schema.org or RDFa for hours data and have noticed that Google or some other search engine has picked it up (i.e., correctly displaying that data as part of the search results)? And if so, how quickly will Google or the like pickup on changes to hours (i.e., shifting between semesters or unplanned changes)?

Re: [CODE4LIB] How to measure quality of a record
Hi, I thought a lot about this question in the past, and my answer is: yes, you can apply statistical formulas. But you should know well each field of your record: what kind of information could they contain, whether you could set rules about that which you can apply for the individual records. Some factors which are important: - the completeness of the records: the ratio of the fields filled and unfilled - the value of an individual field matches the rules or not (say you expect a number in the range of 1 to 5, but you get 6) - the probability that a given field value could be unique - the probability that a record is not duplication of another record Some concrete example from my Europeana past: - there are mandatory fields, and if they are empty, the quality goes down - there are fields which should match a known standard, for example ISO language codes - you can apply rules to decide whether the value fits or not - the data provider field is a free text - no formal rule - but no individual record could contain unique value, and when you import several thousands of new record, they should not contain more than a couple new values - there are fields which should contain URLs or emails or dates, we can check whether they fit for formal rules, and their content are in a reasonable range (we should not have record created in the future for example) - you can measure whether the optional fields are fulfilled, and in which ratio At the end you will have a couple of measurements, and you can apply weighting to calculate a final classification number. You can do a lot to set up rules with faceted search, and of course you can use statistical tools, such as R, Julia which helps to get a picture of distribution of the values. Hope it helps.

Re: [CODE4LIB] How to measure quality of a record
I think a key thing is to determine to what extent any definition of 'completeness' is actually a representation of 'quality'. As Peter says, making sure not just that metadata is present but then checking it conforms with rules is a big step towards this. I would also extend this to assessing at what level of accuracy things have been set, for example dates (a rough range vs a precise day) and geotags (coordinates presenting the centre of Paris vs the exact position that a photograph was taken from). These sorts of things can make a big difference to both the discoverability and practical reusability of records by end users.

Re: [CODE4LIB] Library Hours
Charlie, I don't know of any libraries that have used schema.org for their web site - perhaps others do. If it is used, it should be picked up the next time the search engines index the site. What the search engines do with schema.org is not guaranteed, but can be observed. It is not guaranteed because none of the search engines will say what they do, as that is considered a trade secret (especially from each other). However, as locations and hours are important for their commercial customers (stores, restaurants, etc.) I would expect that to be picked up as a matter of course. Note that already locations and hours for some businesses do show in the search engines, and that is for sites that are not yet using schema.org, so the engines have some way of picking that up from the HTML. The Google side-bar knowledge graph for my local libraries shows Hours https://www.google.com/search?sa=Xbiw=1299bih=561q=san+francisco+public+library+larkin+street+hoursstick=H4sIAGOovnz8BQMDgzYHnxCXfq6-gVlZhbF5sZZ0drKVfk5-cmJJZn4enGGVkV9aVBzLKeznIsHxlTMy2S10V0iJwvZlMgBPWBDOSAei=qhlKVcKWJ8b7oQS65oCQCAved=0CJgBEOgTMBA: Open today · 9:00 am – 8:00 pm javascript:void(0) but I have no idea where that comes from. kc On 5/6/15 5:22 AM, Charlie Morris wrote: I'm curious, Karen, Ethan or anyone else, do you know of any examples of libraries that have implemented schema.org or RDFa for hours data and have noticed that Google or some other search engine has picked it up (i.e., correctly displaying that data as part of the search results)?

I'd like to find out how and why Google is parsing this information.

Right, but I don't think that meets any particular standard, which means that Google is doing a lot of text analysis when it indexes pages, looking for a pattern that looks like opening hours.

Re: [CODE4LIB] Library Hours
I believe the objective, of the search engines, is to be able to provide user useful functionality in both their Knowledge Graphs and on mobile devices for all local businesses. I note now when I search for the local branch of Best Buy or similar on my iPhone I get the 'Open Now' or 'Closed Now' message as part of the result. Karen is right about anyone, including emergency services, being able to harvest this data from your site - mage easier by using a consistent format such as Schema.org. As an aside, the Schema.org community is currently discussing the formatting of opening hours, and consistence with other similar event based timings. It looks like they are going to keep it simple for the moment, returning to issues such as exceptions like open every day 9-5 except Wednesdays in January of a leap year in the near future. Richard.

Re: [CODE4LIB] Library Hours
Hi all, I've been experimenting with schema.org OpeningHoursSpecification, and currently Bing is scraping our hours, but Google isn't. I am using RDFa-lite and I've validated it using a linter (thanks Jason Ronallo!), so I'm scratching my head as to why our hours *still* don't show up on a google search. I suspect part of it for us might be that we're re-branding away from Stockwell-Mudd Libraries to Albion College Library, as it's much more explanatory, but neither search through Google yields a nice box with hours in it like the SFPL. If and when I figure out the problem I'd be happy to send you an update of what we did and what caused it to finally work properly.

Re: [CODE4LIB] Help with Auto Hot Key
Hi Eddie, AutoHotkey can probably do what you want to do. I am not familiar with the Sierra interface, although I have successfully used AHK to automate workflows in a variety of applications. Here's an example of a subroutine with key commands that copy the contents of a CONTENTdm text input box: https://github.com/metaweidner/UHDL_SubjectTopical_CDM/blob/master/UHDL_SubjectTopical_CDM.ahk#L295-303 And check to see if there is was actually any text on the clipboard as a result: https://github.com/metaweidner/UHDL_SubjectTopical_CDM/blob/master/UHDL_SubjectTopical_CDM.ahk#L152-158 I'd be happy to pass along more examples.

I'm hoping someone here is a guru at AutoHotKey! :) We have a clerk that pays our invoices in Sierra. She will write the bib number on a sticky note, as well as the list price and the locations (that each copy will go to). I want to have Sierra copy the bib number, list price, locations, and order record notes onto a receipt and then this clerk would put this receipt with the first copy of the material, rather than hand write on sticky notes all day! Since I had looked, and couldn't find a way to do this easily from Sierra, I had another brilliant idea that we could have Autohotkey copy the fields I want into a template (say, in Publisher) and have the bib number turned into a barcode, and list the other fields that we want that travel around the tech services department. This barcoded bib number would be used by catalogers to enter the bib number in the 949 for overlay in Connexion, and then again by our barcoding clerk to search by bib number in Sierra. At this point, I'm thinking that Autohotkey is my best bet. Here is my prototype of what the routing slip would look like when it's done. The Thickety 2 is a note in the order record put in by our selectors for our catalogers to add that series to the bib record. The 978... is just a placeholder for where the list price will go once we get that field added to our order records: [cid:image001.png@01D08679.A5CC5160] Here is the corresponding order record. Part of my problem for Autohotkey is that not all order records will contain a note (in field z) and the locations may be different (fewer or more) on the LOCATIONS line. I have to include the multi line, because if it's just our Main Library that's receiving the item, then the LOCATIONS at the bottom don't show up at all...just the LOCATION fixed field (under ACQ TYPE).

Re: [CODE4LIB] How to measure quality of a record
Here in .nz the national library runs a local aggregation service http://digitalnz.org/ which has quite good penetration into schools and so forth. It provides some metadata quality reports such as http://metadata.digitalnz.org/nzresearch/127 for sources it aggregates (that report is actually quite a bit dated). My experience of these reports is they're useful in inverse proportion to the diversity of the collection being reported on.

Re: [CODE4LIB] Help with Auto Hot Key
This afternoon, I tried several different methods to print the order record (and order bib) onto receipt paper. That works well--except that it cuts off part of the of the order record note toward the bottom. (we'd prefer to use receipt paper rather than regular computer paper--it's much faster to print and auto-cuts!) Otherwise, I think it would work for my project. When I tried to make the text smaller (from 8 to 6 or 7), it made the font too light and it wasn't readable. Bummer! We're so close!!

Hi, so this is an area that I've done, and am doing, a fair bit of work. See http://stuff.coffeecode.net/2015/ola_white_hat_seo/#/1/10 for some fun slides from a presentation I gave in January at the Ontario Library Association SuperConference that show some ways data gets into Google/Yahoo/Bing and concludes that the OCLC Registry manually maintain yet another copy of your data elsewhere approach isn't working. (Hit s to get speaker notes). The rest of the presentation goes into depth on how to use RDFa to mark up a real library web page with location, contact info, opening hours, and event info. And I've posited that crawling library sites to pull single-sourced data (e.g. you update your website to provide updated hours to humans, and the machines automatically benefit) would be a much more effective, accurate, and usable approach than maintaining copies of the data in Google+, OCLC Registry, etc. We could produce results like http://cwrc.ca/rsc-src/ that stay accurate, rather than being one-off efforts that decay over time. (It would be great if the OCLC Registry had a crawl this URL option so that it could keep all of its data up-to-date and incentive libraries to publish the data in a machine-readable format such as RDFa + schema.org.) On the but that's technically challenging front, I tried pursuing some grant funding to produce templates for publishing that structured info in Drupal, Joomla, and other commonly used CMSs. Sadly, my application was recently denied, but that will only slow me down; I'm not going to give up on the goal. I have a paper in the works that will expand on the content of the presentation for those sites that have the ability (technical and administrative) to modify their own web pages. Sites running the Evergreen library system already generate a page for each of their libraries that contains this structured data (e.g. https://laurentian.concat.ca/eg/opac/library/OSUL), which is single sourced from the data that has to be maintained in the library system anyway. I'll happily acknowledge that getting search engines to harvest the right data is not easy, though: right now, for example, if you search for J.N. Desmarais Library it currently shows that the library is open 24 hours a day, which is completely false--probably maliciously submitted--information. *sigh* I've edited that info in the Google+ page at https://plus.google.com/+JNDesmaraisLibraryGreaterSudbury but even though it is a verified place and I am a manager of the G+ page, the edits still go through approval by Googlers. There appears to be no good way to tell Google Hey, *this* is the URL you are looking for!. Somewhat amusingly, the entire reason I started working with schema.org dates back to an presentation I attended about Google Places years ago, where I whined about having to maintain yet another copy of data in yet another place, and the response inferred that schema.org might be the solution to that problem. Also, due to the structure of university web property ownership, we currently don't have the ability to modify our actual library home page to include any RDFa, which is a *wee* bit frustrating given my work in the field.

Re: [CODE4LIB] Library Hours
I don't know if this could give it a nudge (because as discussed, nobody knows how they work), but you can go into Google Maps (or https://www.google.com/business/ ) and find your place, and claim it with a Google account (you will have to be verified somehow, IIRC usually they will call the contact phone number with a code or something). This lets you put in lots of information that definitely *does* influence the Google results display, often with a card showing location, photo(s), hours, phone number(s), etc. I put ours in some time ago by hand, and it looks like it has updated to our latest regular hours (which have changed since I would have put them in back then). If you enter your hours this way, they will show up in a day or two. You will get a nice looking card in search results. You get Insights and other reports telling you how many times people searched your site, asked for directions, clicked the phone number, etc. And maybe, just maybe, their algorithm will compare that data with data from your site to match it up to automatically update in the future. They're definitely doing some kind of heuristic or guesswork parsing, since when it finds an update (as it did with our hours data, it does ask you to review and verify.

Sergio, I'm hoping the conversations and interest around #metadataquality hashtag: https://twitter.com/hashtag/metadataquality help to move forward some of these conversations from well constructed research projects and academic papers to something that more of us can implement locally in our systems. There are many different ways that we could look at some of these problems and I think having more of us sharing our ideas and possibly code will be great.

As Peter says, making sure not just that metadata is present but then checking it conforms with rules is a big step towards this. I would also extend this to assessing at what level of accuracy things have been set, for example dates (a rough range vs a precise day) and geotags (coordinates presenting the centre of Paris vs the exact position that a photograph was taken from). These sorts of things can make a big difference to both the discoverability and practical reusability of records by end users.

Re: [CODE4LIB] Library Hours
I generally find that Bing makes better use of RDFa/schema.org than Google does. kc On 5/6/15 7:33 AM, Megan O'Neill Kudzia wrote: Hi all, I've been experimenting with schema.org OpeningHoursSpecification, and currently Bing is scraping our hours, but Google isn't. I am using RDFa-lite and I've validated it using a linter (thanks Jason Ronallo!), so I'm scratching my head as to why our hours *still* don't show up on a google search. I suspect part of it for us might be that we're re-branding away from Stockwell-Mudd Libraries to Albion College Library, as it's much more explanatory, but neither search through Google yields a nice box with hours in it like the SFPL. If and when I figure out the problem I'd be happy to send you an update of what we did and what caused it to finally work properly.

We don't know the algorithm for ranking, and we don't know what information they glean from web pages -- and they are unlikely to tell. It is a constant on the schema.org discussion list that developers want to know what Google/Bing/Yahoo/Yandex will do with specific information in the web pages, and it is a constant that the reps there reply: we cannot tell you that.

It would be nice to have a set of use cases to work from. Currently, I'm generating a weekly hours box by pulling JSONP from the hours API of LibCal. I could easily output this in schema.org format (and probably will now), but can Google pick up the information from the DOM if it is delivered as JSON and transformed into HTML? div id=library-hours h2Hours/h2 table class=hours cellpadding=0 cellspacing=0 tr thSun/th thMon/th thTue/th th class=todayWed/th thThu/th thFri/th thSat/th /tr tr td12-5/td td10-6/td td9-8/td td class=today9-8/td td9-8/td td12-6/td td10-6/td /tr /table /div On Wed, May 6, 2015 at 9:47 AM, Karen Coyle li...@kcoyle.net wrote: Charlie, I don't know of any libraries that have used schema.org for their web site - perhaps others do. If it is used, it should be picked up the next time the search engines index the site. What the search engines do with schema.org is not guaranteed, but can be observed. It is not guaranteed because none of the search engines will say what they do, as that is considered a trade secret (especially from each other). However, as locations and hours are important for their commercial customers (stores, restaurants, etc.) I would expect that to be picked up as a matter of course. Note that already locations and hours for some businesses do show in the search engines, and that is for sites that are not yet using schema.org, so the engines have some way of picking that up from the HTML.

For those that don't know the library URL off-hand, it is much easier to find a library website by Googling than it is to go through the central university portal, and the hours will show up at the top of the page after having been harvested by search engines.
