      URL for adding URL, ISBN, DOI, PMID, or arXiv IDs to one's Zotero account.

      I've created a mobile shortcut using the URL Forwarder app to accomplish this with a share functionality after highlighting an ISBN.

      Might also try using https://play.google.com/store/apps/details?id=com.srowen.bs.android&hl=en with the added custom search query custom search URL https://www.zotero.org/save?q=%s to see if that might work as well. This should allow using a scanner to get ISBN barcodes into the system as well. Useful for browsing at the bookstore.

      I should also create a javascript bookmarklet for this pattern as well.

    1. Subject classes do not exist for some of the older archives in the Physics group. Instead, each archive represents a subject class, e.g., hep-ex, hep-lat, hep-ph, and hep-th. The astro-ph archive currently has no subject classes, while cond-mat and physics are classified by subject classes that appear only in the metadata (not in the identifier). This scheme uses two upper-case characters to identify the subject class,
    2. The canonical form of identifiers from January 2015 (1501) is arXiv:YYMM.NNNNN, with 5-digits for the sequence number within the month. The article identifier scheme used by arXiv was changed in April 2007. All existing articles retain their original identifiers but newly announced articles have identifiers following the new scheme. As of January 2015, the number of digits used in the second part of the new identifier, the sequence number within the month, is increased from 4 to 5. This will allow arXiv to handle more than 9999 submissions per month (see monthly submission rates).
    1. shows the primary classification in a standard way, and is also recommended as the preferred citation format
    2. Extension. The new scheme could be extended to use more than 4 or 5 digits for the sequence number. However, that would correspond to more than 99999 submissions per month, or over 10 times the current submission rate, and is thus not anticipated for many years.
      • CODIGO 4-5
    3. Old papers in archives where the archive name matches the primary subject classification (e.g. hep-th) do not have the square brackets with primary subject classification
      • OK, exception in zotero translator
    1. Many bibliography databases supply a DOI (Digital Object Identifier) or arXiv eprint number with BibTeX entries. However, the standard BiBTeX style files either ignore this information or print it without hyperlinking it correctly. Here’s how you can get working clickable links to both DOI and arXiv eprints.
      • BIBTEX standard doesnt use them
    1. For the new style arXiv identifiers (April 2007 and onwards) we recommend these bib-style extensions: **archivePrefix = "arXiv"**, **eprint = "0707.3168"**, **primaryClass = "hep-th"**,
      • for "old style ID":
      • **eprint = "hep-ph/9609357"**
    1. APIs for Scholarly Resources What is an API? API stands for application programming interface. An API is a protocol that allows a user to query a resource and retrieve and download data in a machine-readable format.  Researchers sometimes use APIs to download collections of texts, such as scholarly journal articles, so they can perform automated text mining on the corpus they've downloaded. Here is a simple tutorial that explains what an API is.  Below are some APIs that are available to researchers. Some are open to the public, while others are available according to the terms of Temple University Libraries' subscriptions. Many require you to create an API key, which is a quick and free process.   How do I Use APIs? You can create a simple query in the address bar in a web browser. However, a more complex query generally requires using a programming language. Commonly used languages for querying APIs are Python and R. (R is the language used in the R software.) The examples given in the documentation for the APIs listed below typically do not include sample programming code; they only explain how the data is structured in order to help users write a query.

    1. Encoding an OAI-PMH request in a URL for an HTTP GET URLs for GET requests have keyword arguments appended to the base URL, separated from it by a question mark [?]. For example, the URL of a GetRecord request to a repository with base URL that is http://an.oa.org/OAI-script might be: http://an.oa.org/OAI-script? verb=GetRecord&identifier=oai:arXiv.org:hep-th/9901001&metadataPrefix=oai_dc However, since special characters in URIs must be encoded, the correct form of the above GET request URL is: http://an.oa.org/OAI-script? verb=GetRecord&identifier=oai%3AarXiv.org%3Ahep-th%2F9901001&metadataPrefix=oai_dc

    1. karnesky commented on Sep 1, 2013 A few things to note here: arXiv does have preprints, but a lot of these are linked to journal articles & some people use it as a reprint server. If an arXiv record has a DOI, I would suggest (strongly) that it should be typed as a journal article. We may even just use the ADS link, which seems to have a great BibTeX-formatted record for most eprints (though I'm torn on doing that). NASA ADS and most others classify arXiv eprints as journal articles anyway. Zotero will import any of those as journal articles, so there might be a case to import all arXiv eprints as if they were journal articles
      • ok
    1. However these fields are not filled automatically by zotero when importing from arxiv, instead a Report is created with all three fields (Archive, Loc. in Archive, Call number) empty
      • OK: doesnt work, because:
      • arxiv.js import doesnt fill these fields
      • ADS.js import, doesnt
    2. Further, by trial and error I found that setting the Journal article fields as follows: Archive: arxiv Loc. in Archive: 1234.1231 Call number: hep-ph results in zotero exporting a biblatex file containing: eprinttype = {arxiv}, eprint = {1234.1231}, eprintclass = {hep-ph},
      • TIP: SEE BibLATex.js translator:
      • if (item.archive == "arXiv" || item.archive == "arxiv") {
        writeField("eprinttype", "arxiv");
        writeField("eprint", item.archiveLocation);
        if (item.callNumber) { // assume call number is used for arxiv class
            writeField("eprintclass", item.callNumber);
    3. According to the biblatex manual ftp://bay.uchicago.edu/CTAN/macros/latex/exptl/biblatex/doc/biblatex.pdf section 3.11.7, arxivprefix is an alias for eprinttype and primaryclass is an alias for eprintclass.
      • BIBLATEX: extended fields
      • the are alias
    4. uses in general the fields archivePrefix, eprint and primaryClass

    1. search_query and id_list logic We have already seen the use of search_query in the quickstart section. The search_query takes a string that represents a search query used to find articles. The construction of search_query is described in the search query construction appendix. The id_list contains a comma-delimited list of arXiv id's. The logic of these two parameters is as follows: If only search_query is given (id_list is blank or not given), then the API will return results for each article that matches the search query. If only id_list is given (search_query is blank or not given), then the API will return results for each article in id_list. If BOTH search_query and id_list are given, then the API will return each article in id_list that matches search_query. This allows the API to act as a results filter. This is summarized in the following table: search_query present id_list present API returns yes no articles that match search_query no yes articles that are in id_list yes yes articles in id_list that also match search_query

    3. 5.1.1. A Note on Article Versions Each arXiv article has a version associated with it. The first time an article is posted, it is given a version number of 1. When subsequent corrections are made to an article, it is resubmitted, and the version number is incremented. At any time, any version of an article may be retrieved. When using the API, if you want to retrieve the latest version of an article, you may simply enter the arxiv id in the id_list parameter. If you want to retrieve information about a specific version, you can do this by appending vn to the id, where n is the version number you are interested in.

      Esta API permite obtener datos de una version especifica; la API OAI no lo permite!

    5. For each entry, there are up to three <link> elements, distinguished by their rel and title attributes. The table below summarizes what these links refer to rel title refers to always present alternate - abstract page yes related pdf pdf yes related doi resolved doi no For example: <link xmlns="http://www.w3.org/2005/Atom" href="http://arxiv.org/abs/hep-ex/0307015v1" rel="alternate" type="text/html"/> <link xmlns="http://www.w3.org/2005/Atom" title="pdf" href="http://arxiv.org/pdf/hep-ex/0307015v1" rel="related" type="application/pdf"/> <link xmlns="http://www.w3.org/2005/Atom" title="doi" href="http://dx.doi.org/10.1529/biophysj.104.047340" rel="related"/>

      3 links: 2 always (abs, pdf), 1 if DOI exists

    1. Item = Article Each article in arXiv is modeled as an Item in the OAI-PMH interface. Only the most recent version of each article is exposed via this interface (some metadata formats include the version history).

      VERY IMPORTANT: OAI solo devuelve datos de "ULTIMA" version; no permite acceder a nivel de version; por eso: CAMBIAR a API /api/

    2. 12 April 2007 The arXiv OAI baseURL changed to http://export.arxiv.org/oai2 from http://arxiv.org/oai2. The old URL will issue a redirect for some time but please update your harvester to use the new baseURL.

      IMPORTANT: cambio de URL; usar "export.arxiv"

    3. Metedata formats Metadata for each item (article) is available in several formats, all formats are supported for all articles. The available formats include: oai_dc - Simple Dublin Core. See example in oai_dc format. arXiv - arXiv specific metadata format which includes author names separated out, category and license information. See example in arXiv format. arXivRaw - arXiv specific metadata format which is very close the internal format stored at arXiv. Includes version history. See example in arXivRaw format. You may request a list of all the metadata formats supported with the ListMetadataFormats verb.

    1. Patricio R Estevez-Soto. (2020, November 24). I’m really surprised to see a lot of academics sharing their working papers/pre-prints from cloud drives (i.e. @Dropbox @googledrive) 🚨Don’t!🚨 Use @socarxiv @SSRN @ZENODO_ORG, @OSFramework, @arxiv (+ other) instead. They offer persisent DOIs and are indexed by Google scholar [Tweet]. @prestevez. https://twitter.com/prestevez/status/1331029547811213316

    1. A few months later, in August 1991, a centralized web-based network, arXiv (https://arxiv.org/, pronounced ‘är kīv’ like the word “archive”, from the Greek letter “chi”), was created. arXiv is arguably the most influential preprint platform and has supported the fields of physics, mathematics, and computer science for over 30 years.

      ArXiv (arkaif) adalah contoh lain dari teknologi preprint yang telah dikenalkan sejak tahun 1990.

      ArXiv = bidang fisika, matematika dan sains komputasi.

      Setelah era Arxiv, ada waktu kosong selama 15 tahun tanpa ada perkembangan jumlah server preprint.

    1. Currently, since arXiv lacks an explicit representation of authors and other entities in metadata, ADS must parse author metadata from arXiv heuristically.

      It will be interesting if solving this problem becomes one of hardcore ORCID integration coupled with metadata extraction from submitted manuscripts.

    2. ADS shares those matches with us via its API, and we use that information to populate DOI and JREF fields on arXiv papers.

      I've always wondered if this were true. I continue to wonder if arXiv uses other sources of eprint-DOI matches to corroborate or append to those from ADS.

    1. We are pleased to announce that Steinn Sigurdsson has assumed the Scientific Director position. He will collaborate with the arXiv Program Director (Oya Y. Rieger) in overseeing the service and work with arXiv staff and the Scientific Advisory Board (SAB) in providing intellectual leadership for the operation.

    1. Unsupervised Learning of 3D Structure from Images Authors: Danilo Jimenez Rezende, S. M. Ali Eslami, Shakir Mohamed, Peter Battaglia, Max Jaderberg, Nicolas Heess (Submitted on 3 Jul 2016) Abstract: A key goal of computer vision is to recover the underlying 3D structure from 2D observations of the world. In this paper we learn strong deep generative models of 3D structures, and recover these structures from 3D and 2D images via probabilistic inference. We demonstrate high-quality samples and report log-likelihoods on several datasets, including ShapeNet [2], and establish the first benchmarks in the literature. We also show how these models and their inference networks can be trained end-to-end from 2D images. This demonstrates for the first time the feasibility of learning to infer 3D representations of the world in a purely unsupervised manner.

      The 3D representation of a 2D image is ambiguous and multi-modal. We achieve such reasoning by learning a generative model of 3D structures, and recover this structure from 2D images via probabilistic inference.

    1. When building a unified vision system or gradually adding new capabilities to a system, the usual assumption is that training data for all tasks is always available. However, as the number of tasks grows, storing and retraining on such data becomes infeasible. A new problem arises where we add new capabilities to a Convolutional Neural Network (CNN), but the training data for its existing capabilities are unavailable. We propose our Learning without Forgetting method, which uses only new task data to train the network while preserving the original capabilities. Our method performs favorably compared to commonly used feature extraction and fine-tuning adaption techniques and performs similarly to multitask learning that uses original task data we assume unavailable. A more surprising observation is that Learning without Forgetting may be able to replace fine-tuning as standard practice for improved new task performance.
