I have a webserver and SQL server all running on the same machine. The server runs 4 active websites. 1 of which is very high traffic. The server was rebuilt a few months ago and started working very fast. Now that volume has picked up and processed were added and its slowly starting to hang very frequently. I need to find the source of these problems. I need someone to learn my systems and understand what is happening and give me a solution. I am a programmer but I am not SQL Expert.

This job is focused on advancement of the experience that thousands of users get navigating, browsing, searching and comparing the content offered through our proprietary technology platform. The end-result (output of the ontology model) will be a set of intuitive and comprehensive multi-level navigation structures (hierarchical taxonomies, facets) for browsing, searching and tagging the content offered to our clients. The end-task is envisioned to be primarily achieved with the usage of Semantic Web concepts and data (LOD and other available SKOS) as per Semantic Web standards. The task most likely will require knowledge/learning of several RDF-based schemas (Resume RDF, HRM Ontology, HR-XML, FOAF, SCIOC, Schema.org) and usage of the W3C’s Semantic Web technology stack components (SPARQL, Protege, Semantic resoners). Key tasks: - Definition of RDF Schema and ontologies based on several existing RDF Schemas (Resume RDF, HRM Ontology, HR-XML, FOAF, SCIOC, Schema.org, etc.) - linking available LOD and SKOS data sets, building several core multi-level hierarchical taxonomies (magnitude of tens of thousands of elements) comprehensively describing the content in our system - Rule-based processing and linking of multiple existing, as well as obtained sets of data using semantic reasoners - Definition, structuring and optimization of hierarchical data sets, definition and maintenance of hierarchical relationships of particular terms (facets) - Research (independent, as well as guided by management team) on publicly available SKOS and LOD sets related to the content of the platform from public (international standards, patent databases, public and government databases, various organizational, available XML datasets, etc.), as well as acquired proprietary sources - Retrieval and ETL of multiple additional data sets from multiple sources - Tagging, Classification, entity extraction - Working with management team to maintain and advance particular segments of defined taxonomies Optional Stretch-Tasks (Depending on Candidate's Qualifications): - Automatic analysis of content, extraction of semantic relationships - Auto-tagging, auto-indexing - Integration and usage of selected IBM Watson services for content analysis - Integration with Enterprise Taxonomy Management platforms (Mondeca, Smartlogic, PoolParty, or others) This job will initially require commitment of 15-20 hours per week over 3-6 months engagement. Interaction with a responsible manager will be required at least twice a week over Skype and Google Hangouts. Longer-term cooperation is possible based on the results of the initial engagement. Required Experience: - Detailed knowledge of Semantic Web concepts and techniques - Intimate familiarity with W3C’s Semantic Web technology stack (RDF, SPARQL, etc.) - Hands-on experience with LOD (DB Pedia and others) and various SKOS - Experience of modeling data based on various RDF schemas (Resume RDF, HRM Ontology, HR-XML, FOAF, SCIOC, ISO 25964, etc.) - Knowledge of common open-source ontology environments and tools (Mediawiki, Protege, etc.) or other enterprise-grade ontology tools (Synaptica, DataHarmony, PoolParty, Mondeca, Top Braid, etc.) - Experience of work with semantic reasoners - Prior experience of content management and maintenance of taxonomies for consumer or e-commerce applications Additional Preferred Experience: - Background in Library and Information Science (MLIS), Knowledge Management, Information Management, Linguistics or Cognitive Sciences - Familiarity with common classification systems - Experience working with catalog and classification systems and creation of thesauri - Auto-tagging, auto-classification, entity extraction

Build in GoLang a server application that proxies to a HTTPS website, confirming that the certificate is correct, than extract a webform from that website and displays it to a client within a webpage template.

The form, uses Ajax to update the forms fields with data while the user is filling in the form, this asynchronous functionality shall remain and bypass the proxy communicating directly with the source HTTPS website. The server shall manage multiple sessions when connecting to the source site. A captcha is provided from the source site for each session. You shall program this server to allow multiple sessions all with their own captcha. Upon the user submitting the form, the server shall submit the contents to the HTTPS site, and wait for a response. If success details from the returned data shall be recorded to a json file on the server. On success or fail the feed back from the form shall be displayed to the user. Comment the code.

I am looking for someone that can be available to work with me this Saturday and if need be Sunday also. During CST (USA Central Time). I have about 3,000,000 records that I must analyse. I do not have tools to analyse it. I need to work with someone who has can use data tools to produce tables (and if you can produce graph it will be a big plus but it is not a must). Some of the basic analyses are, how many records contain the word "regulation". I will think of additional questions based on the results that we get from each query. Skills: - must be fast with queries - be able to give results in minutes - must be very good with large data - Help me install tools if possible - be able to manipulate data (Scrape, parse, group, count and more) This will be intense two days work over the weekend. If we work well together it could turn to more work. (if you used MS SQL Server and Azure it will be a big plus​, but it is not essential) Many thanks Fatima
