Retrieving Relevant and Diverse Movie Clips Using the MFVCD-7K Multifaceted Video Clip Dataset
No full textMultimedia search is an emerging area in information retrieval (IR) and recommender systems (RS) research. However, there is a lack of standardized audiovisual datasets that include rich content descriptors, which are a necessity in content-based IR and RS. The contributions of this paper are twofold: First, we present a new multimedia dataset of movie clips, named MFVCD-7K Multifaceted Video Clip Dataset, that comes with low-level and semantic multimodal descriptions of their content (textual, audio, and visual). In addition, we showcase the use of this dataset for a novel content-based video clip retrieval and result diversification task we introduce. We investigate baseline algorithms for retrieval and diversification, and provide experimental results according to relevance and diversity measures. We believe that both dataset and baseline results constitute an important asset for the IR, RS, and multimedia communities

MMTF-14K: A Multifaceted Movie Trailer Dataset for Recommendation and Retrieval
No full text<p>The MMTF-14K dataset provides a stable and extensive source for devising and evaluating movie recommender systems. MMTF-14K contains <strong><a href="https://mmprj.github.io/mtrm_dataset/datasets">audio and visual descriptors</a></strong> in addition to ratings and metadata for 13,623 Hollywood-type movie trailers. The dataset therefore facilitates research on content-based recommender systems, where content refers not only to metadata, but specifically to visual and auditory characteristics of movies. The data comes also with several baselines <a href="https://mmprj.github.io/mtrm_dataset/benchmark">benchmarking results</a> for uni-modal and multi-modal recommendation systems. The dataset therefore facilitates research on movie recommendation. In addition, the rich data supports the exploration of other multimedia tasks such as popularity prediction, genre classification, or auto-tagging (aka tag prediction).</p>
<p>The MMTF-14K dataset has been created as a joint research work by <a href="http://www.ir.disco.unimib.it/yashar-deldjoo/">Yashar Deldjoo </a>(Politecnico di Milano, Italy), <a href="http://www.campus.pub.ro/lab7/gconstantin/">Mihai Gabriel Constantin </a>and <a href="http://campus.pub.ro/lab7/bionescu/">Bogdan Ionescu </a>(University Politehnica of Bucharest, Romania), <a href="http://www.cp.jku.at/people/schedl/">Markus Schedl </a>(Johannes Kepler University Linz, Austria), and <a href="https://scholar.google.it/citations?hl=en&user=dTSOPCMAAAAJ&view_op=list_works&sortby=pubdate">Paolo Cremonesi </a>(Politecnico di Milano, Italy).</p>
<p>We would like to acknowledge MovieLens here for providing a stable benchmark dataset of movies containing individual user ratings and metadata which is an enabler for doing research on movie recommendation. Please consider the <a href="http://files.grouplens.org/datasets/movielens/ml-20m-README.html">MovieLens-20M web page</a> for more details on the ratings and tags datasets.</p>

Platypus variolosus Schedl 1942
No full textPlatypus variolosus Schedl Platypus variolosus Schedl, 1942: 201. Baiocis variolosus (Schedl): Browne 1962: 652. Taxonomy: This species was described in Platypus from the female sex only, but transferred to Baiocis by Browne (1962). Schedl (1967) returned the species to Platypus. The senior author has examined the lectotype (NMW). It belongs in the genus Platypus, and is related to the species group including Platypus lunifer Schedl and P.subdepressus Schedl, being closest to an undescribed species from Borneo. The unknown male may already have been described under another name. Distribution: The species is recorded from West Malaysia and Sumatra. Biology: Unknown.Published as part of Beaver, Roger A., 2018, A review of the genus Baiocis Browne, 1962 (Coleoptera: Curculionidae: Platypodinae), with new species, new synonymy and a key to males, pp. 481-501 in Zootaxa 4434 (3) on page 499, DOI: 10.11646/zootaxa.4434.3.5, http://zenodo.org/record/129227
Platypus transformis Schedl 1936
No full textPlatypus transformis Schedl Platypus transformis Schedl, 1936a: 16 Platypus angusticeps Schedl, 1942: 203. syn. n. Taxonomy: Platypus angusticeps was transferred to Baiocis by Browne (1962: 651), but returned to Platypus by Schedl (1967). Wood and Bright (1992) list the species under Baiocis, and state that there are female syntypes in BMNH, but they are not in that museum, and were evidently not returned by Schedl (see comments in Beaver 1998). The senior author has examined the female specimen incorrectly labelled by Schedl as 'holotype' (NMW). It is a female specimen of Platypus transformis Schedl (specimens examined in BMNH, NMW and RAB). Distribution: The distribution of the species extends from Sri Lanka through Malaysia and the Philippines to the Bismarck archipelago. Biology: Almost all records of host trees are from the Dipterocarpaceae, and the species evidently has a preference for that family (Browne 1961). Browne (1936) records the species attacking large living dipterocarp trees through wounds.Published as part of Beaver, Roger A., 2018, A review of the genus Baiocis Browne, 1962 (Coleoptera: Curculionidae: Platypodinae), with new species, new synonymy and a key to males, pp. 481-501 in Zootaxa 4434 (3) on pages 498-499, DOI: 10.11646/zootaxa.4434.3.5, http://zenodo.org/record/129227
Baiocis inimicus Schedl
No full textBaiocis inimicus (Schedl) (Fig. 11) Crossotarsus inimicus Schedl, 1935: 482. Platypus inimicus (Schedl): Schedl 1958: 152. Platypus velatus Schedl, 1958: 152. Unnecessary new name for P. inimicus (Schedl 1935 nec Broun 1910). Baiocis inimicus (Schedl): Browne 1962: 651. Taxonomy: Schedl (1978) designated a male lectotype from the Philippines in his collection (NMW). This is cited by Wood and Bright (1992). However, the lectotype is not now in the Schedl collection (H. Schönmann in litt.). Schedl (1935) also mentioned " types in the possession of Mr. W. Schultze". The Schultze collection passed after his death to the Staatliches Museum für Tierkunde, Dresden (SMTD). The senior author has examined a male from the Schultze collection labelled with the same data as given by Schedl (1935), and determined by him as Crossotarsus inimicus n. sp. Although not labelled as a type, it evidently belongs to the type series. The only specimen remaining in NMW is a male from Borneo recorded by Schedl (1965) as Platypus velatus. This is not conspecific with the specimen in the Dresden museum, lacking the strong, truncate process on the first ventrite. It may represent an undescribed species. Schedl's (1968) record of the species (as Platypus velatus) from Papua New Guinea (New Britain) must also be regarded as doubtful. A male and a female from the Philippines in BMNH determined as this species by D.J. Atkinson belong in the genus Dinoplatypus Wood. Distribution: Known with certainty only from the Philippines. Biology: Unknown.Published as part of Beaver, Roger A., 2018, A review of the genus Baiocis Browne, 1962 (Coleoptera: Curculionidae: Platypodinae), with new species, new synonymy and a key to males, pp. 481-501 in Zootaxa 4434 (3) on page 495, DOI: 10.11646/zootaxa.4434.3.5, http://zenodo.org/record/129227

Baiocis angustiformis Schedl
No full textBaiocis angustiformis (Schedl) (Fig. 10) Platypus angustiformis Schedl, 1942: 202. Baiocis angustiformis (Schedl): Browne 1962: 651. Taxonomy: Only the male of the species is known. The senior author has examined the male lectotype (NMW). New Records: MALAYSIA, Sabah, Sipitang, Mendolong, 11.iv.1988 (S.Adebratt) (1 male); as previous except: 25.iv.1988 (1 male). The specimens have been compared with the lectotype (NMW). Distribution: East and West Malaysia. Biology: Recorded only from Annonaceae sp. (Schedl 1942, Browne 1961).Published as part of Beaver, Roger A., 2018, A review of the genus Baiocis Browne, 1962 (Coleoptera: Curculionidae: Platypodinae), with new species, new synonymy and a key to males, pp. 481-501 in Zootaxa 4434 (3) on page 493, DOI: 10.11646/zootaxa.4434.3.5, http://zenodo.org/record/129227
