We complemented the generic flux-limited spectroscopic surveys at 11 {mu}m and 15 {mu}m, with additional sources selected based on the MIR and optical colors. In MMT/Hectospec observations, the redshift identification rates are ~80% for objects with R &lt; 21.5 mag. On the other hand, in WIYN/Hydra observations, the redshift identification rates are ~80% at R magnitudes brighter than 19 mag. The observed spectra were classified through the visual inspection or from the line diagnostics. We identified 1128 star-forming or absorption-line-dominated galaxies, 198 Type-1 active galactic nuclei (AGNs), 8 Type-2 AGNs, 121 Galactic stars, and 190 spectra in unknown category due to low signal-to-noise ratio. The spectra were flux-calibrated but to an accuracy of 0.1-0.18dex for most of the targets and worse for the remainder. We derive star formation rates (SFRs) from the mid-infrared fluxes or from the optical emission lines, showing that our sample spans an SFR range of 0.1 to a few hundred M_{sun}_/yr. We find that the extinction inferred from the difference between the IR and optical SFR increases as the IR luminosity increases but with a large scatter.</description><source format="bibcode">2013ApJS..207...37S</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/207/37</referenceURL><type>Catalog</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/TAP">TAP VizieR generic service</relatedResource></relationship><relationship><relationshipType>IsServedBy</relationshipType><relatedResource>Conesearch service</relatedResource></relationship><relationship><relationshipType>related-to</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/548/A29">J/A+A/548/A29 : IR source catalog of AKARI NEP-Wide field (Kim+, 2012)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/537/A24">J/A+A/537/A24 : AKARI NEP-Deep field mid-IR source catalogue (Takagi+, 2012)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJS/190/166">J/ApJS/190/166 : Optical catalog of AKARI NEP-wide survey (Jeon+, 2010)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/517/A54">J/A+A/517/A54 : 20cm survey of the AKARI NEP (White+, 2010)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/PASJ/59/S529">J/PASJ/59/S529 : NEP deep survey at 11um (Lee+, 2007)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/ApJS/172/583">J/ApJS/172/583 : NEP source catalog (Hwang+, 2007)</relatedResource></relationship></content><rights>https://cds.unistra.fr/vizier-org/licences_vizier.html</rights><capability><interface xsi:type="vr:WebBrowser"><accessURL use="full">https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/207/37</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/207/37</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/207/37</mirrorURL></interface></capability><capability><interface xsi:type="vs:ParamHTTP"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/207/37</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/207/37</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/207/37</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface></capability><capability standardID="ivo://ivoa.net/std/TAP#aux"><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://tapvizier.cds.unistra.fr/TAPVizieR/tap</accessURL></interface></capability><capability xsi:type="cs:ConeSearch" standardID="ivo://ivoa.net/std/ConeSearch"><description>Cone search capability for table J/ApJS/207/37/nepspec (Optical redshifts catalog over NEP-Wide Survey and line flux measurements)</description><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/207/37/nepspec?</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/207/37/nepspec?</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/207/37/nepspec?</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface><maxSR>180.0</maxSR><maxRecords>50000</maxRecords><verbosity>true</verbosity><testQuery><ra>266.81525</ra><dec>66.4315</dec><sr>0.005555555555555556</sr></testQuery></capability><coverage><spatial>5/2901 4010 6/10237 10239 11613 15358 15359 16046</spatial><spectral>2.762881831355591e-19 3.3785437584409506e-19</spectral><footprint ivo-id="ivo://ivoa.net/std/moc">https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/207/37?format=ascii</footprint><waveband>Optical</waveband><waveband>Infrared</waveband></coverage><tableset><schema><name>default</name><table><name>J/ApJS/207/37/nepspec</name><description>Optical redshifts catalog over NEP-Wide Survey and line flux measurements</description><column><name>recno</name><description>Record number assigned by the VizieR team.
